About Horizon Mirage
VMware Horizon Mirage offers a unique solution for managing physical laptops
and desktops that combines centralized management for IT and local execution for
end users. When Mirage is installed on a Windows PC, it centralizes a complete
virtual copy of that end point to the data center and keeps it synchronized. The
synchronization includes changes from a user's Windows PC being uploaded to the
data center, and changes from IT being downloaded and applied directly to the
user's Windows PC. Horizon Mirage enables central image management of desktops while
still allowing local execution at the user end point.
Horizon Mirage 4.2.3 is a maintenance release focused on internal mechanisms to enable better handling of storage disconnects.
This version provides the following new features and improvements:
- Better storage disconnects handling - Horizon Mirage servers now identify high load conditions on storage that can cause disconnects
and can throttle down to allow storage utilization to return to normal.
- SSL configuration option in Horizon Mirage server installation - The IT manager can now configure SSL communication during server installation.
There is no need to perform this operation with the Management console after installing.
- Branch reflector enhancements - The IT manager can better design and monitor branch reflector deployment
by simulating the branch reflector selection on endpoints.
The IT manager can now click any device from the Management console and see if it has a branch reflector in its vicinity.

Known Limitations with Horizon Mirage 4.2.3
The following limitations are known in this Horizon Mirage release.
- Horizon Mirage supports up to 1,000,000 files per CVD.
- Local users on a reference machine are not deployed through in a base
layer, except when used in Windows 7 migration. In image assignment and layer
updates only the default local user profile is deployed. Applications
requiring the creation and usage of local user profiles are not suitable for
inclusion in a base layer.
- During streaming restore, applications will fail to access offline files
before the Horizon Mirage service has started, which might impact their normal
operation. You can extend the minimal restore set to accommodate these
particular applications. For further details refer to the Horizon Mirage
- All changes to the CVD on the server (base layer assignment, policy
change) will propagate to the client only on the next synchronization interval
(by default, 1 hour, customizable by policy). Use the Sync Device action from
the management console or the Sync Now action from the endpoint device to
- If the machine account password has expired after a restore operation, you
might not be able to connect to the domain. This is a common issue with Active
Directory and backups. See http://support.microsoft.com/kb/175468
for resolution and more details.
- Horizon Mirage requires the default Windows Shadow Copy provider 1.0. In order to
view the VSS providers installed on the computer use the following command
line: vssadmin list providers.
- Horizon Mirage does not support the Windows Fast User Switching option and it must
be disabled on the endpoint and reference machines before capturing a base
- Horizon Mirage will only upload and store the main NTFS stream of a file. All
other streams are not uploaded to or restored from a CVD.
- PST file changes are uploaded from the endpoint into the CVD once a day.
To ensure that the PST file is successfully uploaded to the CVD before
performing restore of a CVD to a new hardware, reboot the client and click on
Sync Now. As a result, the PST file will be uploaded, and then you can proceed
to the reassignment operation.
- Kaspersky antivirus - please contact Support for deployment instructions.
- Sophos SafeGuard - please contact Support for deployment instructions.
- Clients with multiple volumes
- Content of non-fixed drives (network maps, volatile devices such as
Disk-on-key) will not be uploaded to the server.
- When assigning a Base Layer to the endpoint, Windows fixed-drive letters
on the endpoint must be the same as on the reference machine from which the
base layer was captured (for example, it cannot be C: on a CVD and D: on a
- By default, only the system volume is uploaded to the CVD. You can add
volume drive letters to the upload policy to upload additional volumes.
- Base layering and app layering do not currently support SQL Express/SQL Server.
Known Issues with Horizon Mirage 4.2.3
The following known issues affect the Horizon Mirage 4.2.3 release:
Horizon Mirage Client
On base layer or app layer updates,
Horizon Mirage does not force automatic activation of Office 2010 keys
if the CVD did not have any Office 2010 product before the operation.
Activation can be invoked manually and might be invoked automatically by Office 2010.
Activate Office 2010 manually (via the Office 2010 menus).
Restoring a CVD into a device while it is downloading and applying Windows
Updates might lead to Windows problems.
Make sure that Windows Update is disabled throughout the restore operation.
When migrating to Windows 7, some start menu items might not be migrated to the new system.
It is not always desirable to transfer all start menu items on a migration
since some applications in the original system might not be available in the new system.
You can contact support to provide a USMT with a custom XML which transfers start menu items.
Performing a Horizon Mirage restore or base layer update operation when the target
device and the CVD or base layer contain the McAfee DLP Agent
might lead to an endless loop of Horizon Mirage retries.
This can be corrected in the following ways:
- Disable or uninstall the McAfee DLP Agent during the operation.
- If possible, add the Wanova.Desktop.Service.exe to the McAfee safe list.
In very rare cases, after migrating an ESX VM from Windows XP to Windows 7
and then reverting the machine back to Windows XP, a black screen with a solid cursor might appear on boot.
This can be corrected in the following ways:
- Convert the ESX VM to a VMware Workstation machine.
- Contact support to receive instructions on how to install the Windows 7 boot loader
instead of the Windows XP boot loader.
In very rare cases, file system corruption might cause Horizon Mirage to enter an endless loop of restore attempts.
Try to run chkdsk to fix the file system.
Adding rules to the Unprotected Area in the upload policy might prevent you from properly restoring CVDs.
For example, if you unprotect "*.bin" from %anyvolume% (with recursive=true),
these files will not be uploaded to the CVD (including files like that files in c:\windows, c:\program files).
If you later restore the CVD, Windows might fail to operate correctly.
Fix the upload policy by unprotecting only files which are not required by the operating system.
Horizon Mirage might fail to import drivers into the driver library if they contain
unconventional operating system version information, such as:
Try to use an alternative driver package (for example, of a previous version)
which does not contain this version information.
- The VSS snapshot during final phases of the layer
update operation might fail with a Shim execution failed to complete

- On layer update operations, the Horizon Mirage Management
console Transactions view might show transactions for base and app layers that
were not changed in the layer update operation.
This can be

CVD through the File Portal. Opening CVD properties > File Portal
shows the user under Local User but File Portal User is
- Log out the user and log in again on a remote machine when Horizon Mirage is connected.
- Manually add the user name to the File Portal User column.
- In rare cases, at the first Windows startup after
applying a base layer, the Horizon Mirage user experience might degrade slightly for the
first few minutes after startup.
- Rebooting the machine while the Horizon Mirage client is
being upgraded/installed might leave the Horizon Mirage client in an inconsistent

script (available from the VMware support team) and then reinstall the Horizon Mirage
- Windows system restore points do not work on
machines installed with Horizon Mirage.
- After a Selective Restore, a new user profile
might be created for a preserved user profile. This only happens when
restoring between a CVD that does not include the specified user to a device
that does have the user profile. This is mainly relevant when restoring to an
older snapshot that does not include the user profile. In this case, when the
user logs in, he will have a new user profile but without its

will malfunction and automatically restart and retry the operation.
- In rare cases, a post base layer script failure
will not be reported at the server. This can happen if the post base
layer script runs before the client is connected to the server.
- Unprotected folders are uploaded by Horizon Mirage (only
folders, not the files). This is due to Recursive rules in the policy that
apply on the same folder in unprotected include and unprotected
exclude, causing the inner folders to be protected.
- File Level Restore (FLR) on offline files during
streaming is not supported.
- Restarting a client machine during Horizon Mirage client
upgrade might cause the Horizon Mirage client to be removed from the machine.
Manually install the Horizon Mirage client. If the Horizon Mirage client fails to
install, contact the VMware support team.
- After reverting back from a Windows 7 snapshot to a
Windows XP snapshot with a different bitness type, Horizon Mirage can't be uninstalled.
Contact the VMware support team.
- The status window flickers between startup steps
and streaming. After the pivot process, when the client starts the
ignition steps and streaming, the status window reports both states
- In the User State Migration flow, local accounts
on the source machine are not migrated to the new machine.
- Open with does not work during

- Reverting back from Windows 7 to an Windows XP OS might leave
some Windows 7 directories on the machine, such as Program files
- When performing a Windows XP to Windows 7 migration or a Windows 7 to Windows 7 user profile migration,
and there is a profile with a folder name longer than 20 characters that isn't located in the default profiles folder,
USMT might fail to complete.
Remove the long user profile name from the non-standard location before performing the operation. Contact VMware technical support for further assistance.
- In rare cases, Horizon Mirage might not complete a restore operation Prefetch phase or Streaming phase.
This can happen if some files in the same directory have conflicting names, for example,
file1 is called DESCRI~1.HTM and file2 is called description.htm.
Add one of the conflicting file names to the Unprotected area or Do Not Restore area of the master policy.
Contact VMware technical support for further help to confirm the reason for the restore failure.
- Horizon Mirage currently cannot base layer provision a machine
if the provisioned base layer contains more than one volume.
Contact VMware Technical Support for assistance.
- A machine that is restored with streaming may fail to detect NVIDIA drivers on Plug and Play,
leaving the machine installed with only the Windows video drivers.
Reinstall the NVIDIA drivers manually.
- In rare cases, Horizon Mirage might fail a download operation
because a non-system drive included in a multi-disk base image was not detected as a fixed drive.
Reboot the machine to resume the download operation.
- In rare cases, when migrating a device from Windows XP to Windows 7,
Windows Plug and Play may take too long to install some drivers, resulting in a timeout that stops their installation.
Contact VMware technical support for instructions on how to disable
the PnpTimeoutShim parameter
- After a rebase failure,
or if Mirage fails to download a driver library from a branch reflector,
the local user sees the Idle status instead of a special status.
A workaround is not currently available.
- In very rare cases during a Windows 7 migration,
Horizon Mirage might not finish downloading files. The system stays in migration state but without progress.
Restart the machine.
- If the client machine runs out of RAM,
or an I/O error occurs on the page file,
Horizon Mirage may lose its server state and go into Pending Restore mode.
Reboot the machine and force upload.
- A Windows XP to Windows 7 in-place migration operation
might result in a 0x0000007b stop message if the Windows 7 base layer or the driver library used
does not contain the correct drivers for the target's disk controller.
Verify that the correct disk controller drivers are installed in the Windows 7 base layer or the Horizon Mirage driver library.
Contact VMware technical support for further assistance.
- Applying a base layer that does not include Visual Studio Tools for Applications
to a machine whose previous base layer did include it might cause the local user-installed Visual Studio not to function.
Capture the new base layer with Visual Studio Tools for Applications.
Horizon Mirage Client - Application Compatibility
- By default, Horizon Mirage does not protect *.nsf files,
which might lead to Lotus Notes errors when trying to open .nsf files (for
example, name.nsf) after restore operations.
Change the upload
policy to include *.nsf files in the protected area.
- After removing the CA Internet Security Suite
(2010 version and later) using the Horizon Mirage app layer or base layer mechanism,
the network might not be available.
Run netsh winsock
reset using the command line (as administrator) to restore the network to
- Distributing the McAfee Agent with an app layer
or base layer when a different version of McAfee Agent is already installed in
the CVD might lead to duplicate McAfee Agent entries in add/remove
Revert the CVD to a snapshot from before the layer
was applied and update the McAfee Agent manually.
- Delivering Altova XMLSpy with an app layer might
remove the association of .xlsx and .pptx files to Excel/PowerPoint.
Manually change the associations by using Open
- Delivering Apple applications (for example,
QuickTime) with a layer to a CVD which has an Apple application (for example,
iTunes) of a later version might cause the application in the CVD not to launch
or function as required.
Capture a new app layer with the latest
version of the Apple application you are trying to deliver and use it instead
of the older layer.
- Applying a layer with CA Internet Security might
leave the machine without the CA Internet Security firewall properly
Re-install CA Internet Security manually.
- After delivering Symantec Endpoint Protection v12
with a layer, the Symantec teefer network component might not be
For Symantec Endpoint Protection - Consumer
version: Turn Off the Symantec Tamper Protection option with Change
Settings > Client Management, and clear the Tamper Protection
For Symantec Endpoint Protection - Managed/enterprise version:
Add an exception for Wanova.Desktop.Service.exe as described in http://www.symantec.com/business/support/index?page=content&id=HOWTO55213#v39871590.
- Horizon Mirage cannot distribute the Alcohol 120%
software via a base layer update as it does not break current installations on
- After removing the Sun Java Runtime Environment
via a base layer update on a 64-bit machine, a problem arises when
reinstalling the same version.
Install a newer version of the
Java Runtime Environment or manually delete the key:
- The AutoPlay menu might show multiple options after
a base layer update.
- When a new version of an already installed
application is installed from a base layer, the application conflict report
might indicate that the application is being installed and not updated.
- Upgrading Office 2007 to Office 2010 on a user
machine that has Visio installed prevents the user from uninstalling Visio
2007 in future.
Run repair on the Visio 2007 and then uninstall
- When a base layer is assigned during Centralize
end point, application conflict warnings do not appear.
- Visio 2007 is not activated after a base layer
update with Office 2007.
Clean the Visio product leftover from
the base layer, see http://support.microsoft.com/kb/895456.
- Horizon Mirage does not support downgrading Office 2010
to 2007 through the base layer mechanism.
- The Program List in MMC might not show applications
which are listed under the following registry key in the CVD:
- Unactivated Office applications might also appear
in the list of Office applications during the capture base layer wizard
- Following a rebase of a CVD with pending WUs, WU
failure might occur.
Ignore the WU failure and re-check for WUs
- If Enforce Core Image with user application
removal is performed on a CVD that has Google Chrome installed by the user and
configured as default browser, the machine will be left without a default
Select another browser as the default browser.
- After Windows 7 migration, the target device has the
same client Machine ID as the reference machine.
generate a new CMID using: cscript c:\Windows\system32\slmgr.vbs
- When a base layer that was captured on an
ESX machine with ESX VMware tools is assigned to a Fusion machine, a BSOD
error might occur. This happens because a version of VMware tools ESX is
installed on the Fusion machine.
Do not install VMware tools on
the ESX reference machine if you want to use this reference machine to manage
Fusion machines as well. Use the post base layer script to install VMware
tools, or install VMware tools on the Fusion machine before applying the base
- Assigning a base layer with McAfee on a Fusion VM
causes no network connectivity.
The VMware support team will
supply a script that must be installed in the reference machine before
capturing the base layer.
Horizon Mirage Client - Device Drivers
- Ghost devices might appear in the
Device Manager after migration/base layer update.
This does not
affect the user in any way. The device can be removed manually using Device
Manager or a post migration script.
- After a base layer update, a problem occurs when
installing drivers from the Driver Store. This can happen if the Reference
Machine has a driver installed with the same name but a different binary than
the one included in the Driver Store (e.g SoundMAX Audio Driver).
Uninstall all unnecessary drivers from the Reference Machine.
- After a rebase to VM, some Virtual Devices are
not installed (Pointing Device, Audio and USB hub).
A post base
layer script is available to fix this issue. Contact the VMware support team.
- During a restore, in some rare cases, the user
will be unable to logon. This happens if installation of the keyboard driver
plug-and-play requires a system reboot.
Perform a hard reboot of
Horizon Mirage Server & Management Server
A device that is configured to be a branch reflector will malfunction if it runs out of disk space. If the cache size is configured to be greater than the amount of available disk space, the branch reflector will use up all available disk space, eventually causing a malfunction.
Ensure that enough free disk space is available when configuring the branch reflector cache size.
If the device malfunctions, it is recommended to free some disk space and restart the desktop service.
When running a CVD integrity report on a loaded storage, an error might appear, stating:
"Unable to verify [filename] - The process cannot access the file because another process has locked a portion of the file(33)"
In this situation, not all files have been properly scanned by the CVD integrity report.
Run the CVD integrity report again to ensure the relevant file has been checked.
- On deployments where the AD server does not support built-in recursive queries, Horizon Mirage will fail to detect group membership correctly for domain groups. This will cause installation failure if the supplied default group is a domain group, and will cause a post-installation login failure for users relying on such groups for permissions.
Use local groups instead of domain groups for Horizon Mirage permission
- In rare cases, when a volume is disconnected, the
Revert to Snapshot operation might stall in the middle, without the ability to
proceed or to be cancelled.
A workaround is currently not available.
- The driver import process might fail due to Horizon Mirage
being unable to parse the INF file. As a result, the driver will not
be a part of the driver library and cannot be delivered by Horizon Mirage.
Use alternative ways to deliver the driver to the end point. For
example, include it as part of the base layer, distribute it using other
distribution software, or install it manually.
- Due to an NTFS compression limitation, do not use
NTFS compression with Horizon Mirage server storage volumes in large deployments. See
- The Server can exceed Maximum Connection if
multiple clients try to connect at the same time. This issue is mitigated by
the fact that the window of opportunity is small and hence the occurrence of
excessive connections will be quite limited.
devices from the server.
- A non-empty volume cannot be added as a Horizon Mirage
storage volume (even if it only includes the automatically created 'System
Volume Information' folder).
Create a directory on the volume and
add the new directory as Horizon Mirage storage.
- During a CVD restore, if the volume on which the
CVD is located in the server fails for any reason, the CVD will move to
Suspend mode. After resolving the volume problem, the IT manager
should resume the CVD and re-confirm the restore operation.
- If the IT manager performs a force remove to a
volume where the USMT library is located, the system will continue to allow
the IT manager to choose U migration although no USMT is present. The
operation will fail, the end result being that the CVD will be connected to
the new device without the user data moving to the right place.
- Horizon Mirage server installation fails if Microsoft.NET
Framework 4.0 is installed.
Uninstall .NET 4.0 and install
Microsoft.NET Framework 3.5.
- The migration task Download phase might seem stuck
at 100% for a long time. This is normal behavior due to Horizon Mirage
performing actions on files on the target machine, and should be ignored.
- The client is returned to pending restore after a
disconnect during force upload.
Perform the force upload
- USMT 4.0 migration from x86 to x64 results in
corrupted COM+ components.
- During a first upload operation,
if Force Upload is used and Enforce Layers is attempted,
the error message indicates that the CVD is in a restore operation instead of a force upload operation.
The user can ignore this warning.
- When you capture a base layer
that includes a Microsoft Office application that requires a license,
the capture wizard might not ask for the license key.
As a result, the Office license can be invalid when the base layer is distributed to endpoints.
If the Wizard does not ask for the license key,
restart the reference machine after the Microsoft Office installation, or perform a manual synchronization.
In the Management console, expand the Image Composer node, select Reference CVDs,
right-click the reference CVD and select Sync Device.
- The Microsoft Management command line interface (CLI) does not support unicode names and descriptions.
Use an ASCII-based name in the CLI, or perform the action through the Horizon Mirage Management console.
- During a Windows XP to Windows 7 migration,
after the target device finishes downloading the image but before it reconnects to the server as a Windows 7 machine,
the device is effectively a Windows 7 machine but the device state on server is not updated yet.
During that time interval, if you revert the device back to Windows XP and System Only Revert is indicated,
the validation does not warn of a problem. The revert eventually fails on the desktop and generates an event.
When reverting a machine from Windows 7 to Windows XP, verify that the System Only option is unchecked.
- When updating app layers for CVDs that also include unchanged layers
(present on the CVDs both before and after assignment),
those CVDs are mistakenly included in both the Assigned and Pending Assignment column counts in the App Layer view.
As the devices finish uploading after the assignment, those CVDs with unchanged layers are no longer included in the Pending Assignment count.
A workaround is not currently available.
- In some cases where meta-data changes occur in system files,
CVD incremental upload might fail in a loop, with the CVD transaction log showing an IncorrectManifestData error.
Wait for the automatic CVD integrity to run for this CVD, or trigger the CVD integrity report manually.
From the Horizon Mirage Management console, under Reports, select CVD Integrity.
Horizon Mirage Management Console
The Horizon Mirage CVD auto-create option allows the administrator to specify a
customized message. A message of more than 200 characters is truncated by the Horizon Mirage UI.
Use a message length that is less than 200 characters.
In certain cases of network disconnects between MMC client and Horizon Mirage servers,
the validation step of Horizon Mirage wizards becomes stuck and does not return control to the user.
Restart the MMC.
When trying to delete a base layer that is in use, the error message
does not include the layer name. It shows only its ID.
A workaround is not currently available.
In the Update App Layers wizard app layer selection step, when already selected items are clicked,
the layer properties panel at the bottom might not update.
Select another app layer in the same panel, then reselect the app layer you want.
- When using the MMC's common wizards' Disaster Recovery to replace a
hard disk, it is not possible to restore only the system without restoring the user data.
There are two ways to restore only the system:
- Go to the Pending Devices list from the inventory tree.
- Right-click the desired device and select Confirm Restore.
In this wizard the Restore System Only option will be selectable.
- Go to the All CVDs list from the inventory tree.
- Right click the desired device and select Restore.
In this wizard the Restore System Only option will be selectable.
The MMC does not respect Windows Location settings for number formatting. The
Digit grouping symbol is a comma (',') and the decimal symbol is a period ('.'),
regardless of Windows Location configuration.
There is no current workaround.
When generating a program list report, the report page's "Generated on:" time is UTC and not local.
There is no current workaround.
When using a Chinese localized version of Windows and running the MMC,
the dashboard view might have some overlapping text.
There is currently no workaround for the Chinese localized version of Windows.
- The Horizon Mirage Management console doesn't update the
status and progress of tasks in the Task Monitoring view. Clicking Refresh
triggers loading but the loading never completes.

- The Assigned Devices view might present an error
pop-up window when performing a quick search for device by its CVD ID.
Hide the CVD column from the view and use the filter panel to
search for the relevant devices.
- A Horizon Mirage upgrade might fail with an unclear message
when the user installing it doesn't have the permissions to access the Horizon Mirage
Verify that the user performing the upgrade is a member
of a group defined with the Administrator Role.
- System only Restore is available during a rebase
operation. When using System only Restore with a rebase, the target machine's
local User Area is preserved and replaces the CVD User Area, causing loss of
data from the CVD.
Do not use Selective Restore with rebase.
- When performing a migration operation on a device
in Restore Streaming state, the migration starts immediately at the end of
streaming without forcing an upload on the new machine.

- When restoring a reference machine from a base
layer, the operation seems to start but the CVD is suspended until the server
copies the base layer files to the CVD.
Wait for the server to
finish copying the files.
- The Program Inventory displays out-of-date
information after a base layer update/rebase operation before the first
Wait for the first upload to complete (can be forced by
Sync Device in management).
- Changing the Upload Interval via Upload Policy
only takes effect after the next Upload Interval.
Wait for the
next upload to see the new settings take effect.
- When attempting to update a filter based on
Active Directory Groups, only groups present at the time the filter was
created are offered.
Remove the filter and create a new filter.
The list of Active Directory Groups will be refreshed.
- Move CVD Task might reach 100% but is not finished.
Wait for the task to reach done state.
- Horizon Mirage Management console supports only the
following resolutions: 1280x800, 1440x900, 1680x1050.
- The Set driver library operation is not supported
while another operation is running on the CVD. No blocking or warning occurs.
Re-apply the driver library set operation.
- When importing new drivers to the driver library
while preserving the folder structure, the drivers do not immediately appear
under the Driver Library node.
Refresh by pressing F5.
- A false server communication error might be
displayed on the Management console. This can happen if the
management console is open for a long time. The error can be safely ignored.
- When assigning a base layer with Antivirus or Anti-Spyware products,
the Horizon Mirage Management console can mistakenly warn the user about Anti-Spyware Products mismatch.
Proceed with the assignment. The warning has no effect on the operation.
- When connecting the Horizon Mirage Management console to the Horizon Mirage system,
if add a system IP address that is not valid to the Management console tree root, the Management console might stop operating.
Restart the Management console and provide a valid IP address.
- When system configuration is attempted using the Horizon Mirage Management console System Settings, but the system is not yet licensed or the license expired, the configuration operation fails due to license validation, without clear indication of the reason to the user.
Provide a valid license key.
- Editing the properties of a static collection
selected from the Management console Collections list in the middle pane of the console window
may result in a loss of static property information and can make this specific collection unusable.
Avoid the problem by opening the collection editor window
from the tree on the right side of the console,
instead of from the list in the middle pane of the console window.
If the problem is already present, you must redefine the static collection.
Horizon Mirage Web Manager Console
When an error page is displayed, the error message is not translated to different languages.
When an error message is displayed, do the following:
For more in-depth error messages, the administrator can refer to the application logs (also in English).
- Log-in again.
- Try to create the same operation again.
- If it fails, contact your administrator.
Horizon Mirage File Portal
- A wrong error message is generated when
management service is not available. The end user is notified of a bad
username or password although the problem is actually that the management
service is down.
- In rare cases, the end user might not
receive the Web Portal registration window if he logs in to the machine before
the Horizon Mirage service was able to connect to the server.
- In rare cases, Webinstall might fail with the error
message: MSI failure. Error: INSTALL_FAILURE.
Resolved Issues in the VMware Horizon Mirage 4.2.3 Release
The following issues have been resolved since the last Horizon Mirage release:
- Reverting to a Windows XP CVD snapshot after
migrating the client to Windows 7 will leave some Windows 7 directories on the
- The Check Reference Machine menu option is
missing from the Admin Tools menu on a Pending reference device in suspended
mode. This happens only if the device becomes disconnected after being
- Client upgrade might fail after uninstallation of
McAfee enterprise A/V version 8.8. When the McAfee software is uninstalled
from the end user machine, it leaves its vb_script scan module registered in
the registry (in a corrupted state). This means that the vb_script can't be
executed by the Horizon Mirage MSI installer and prevents the Horizon Mirage client from being
- Plug-and-play driver installation during
streaming might fail for drivers that require access to offline files during
- Delivery of Corel Draw with a layer might lead to a
one-time configuration screen when the application is launched on the end
- Auto-updating the Vipre anti-virus (from Vipre)
after it was delivered from a layer, then removing this layer, might leave
leftovers of Vipre in the machine, resulting in an error dialog
- In rare cases, applying a layer with a new
version of Firefox on a machine with an older version of Firefox might lead to
Babylon errors (mozglue.dll not found).
- When "branchPeersNoFallbackToServer" is configured to 'True' a branch reflector
will not download base images from the server except for BI caching operations.
This might cause problems when assigning a unique base image to branch reflectors.
In addition, the device status might appear as "Waiting for Branch Reflector"
whether or not the client is actually downloading).
- If Microsoft's Volume Shadow Copy Services do not operate correctly,
Horizon Mirage will fail to complete most operations (e.g. upload, restore, migration).
- If the WMI service is malfunctioning,
a restart might be required for the Horizon Mirage client to reconnect to the server.
- In rare cases involving storage outages, a CVD Move task can become stuck
while Horizon Mirage reports large counts of SIS inconsistency events.
- In the Web Manager dashboard view, the refresh time of the components might differ.
This can cause differences of information between open and closed tiles.
