Workstation Cannot Share a Host with Other VMware Products
You cannot have VMware Workstation installed on the same host machine with another VMware product, such as VMware GSX Server, VMware ACE, or the VMware Virtual Machine Console. The only VMware product that can share a host machine with Workstation is the VMware VirtualCenter client software. If you plan to install VMware Workstation on a host machine that already contains another VMware product, you must uninstall that product first.
