For those, who failed to install fresh VMWare Workstation because old installation failed to uninstall.
In that case the message usually appears:

"the older version of vmware workstation cannot be removed"

Below is universal recipe to handle the errors like that:

1. Try to install new version. If it fails look for the error in installation log file:

see Location of VMware View log files (1027744)

2. Examine found error, if it says cannot find msi for product, find and remove all related entries for this in registry.

3. goto 1

That's all ! It works !
