VMware Tools Upgrade on a Virtual Machine with Wyse Multimedia Support Installed Fails (1001531)
If you provide the optional INSTALL_WYSE=1 command-line parameter during VMware Tools upgrade on a virtual machine that already has the Wyse Multimedia Support DLLs installed, the upgrade fails. The INSTALL_WYSE=1 command-line parameter should be used only for first-time installation of Wyse Multimedia Support.
Do one of the following:
Issue the setup command for upgrade without the INSTALL_WYSE=1 command-line parameter.
Use Add or Remove Programs in the guest operating system to repair the Wyse Multimedia Support installation.
