Uninstall VMware Workstation v8.04 completely from Windows 7
===

I wanted to uninstall Wmware v8.04 from my window 7 64bit. I could not do that from control panel. I received "The MSI failed" error like: http://www.sysprobs.com/fixed-the-msi-failed-vmware-workstation-uninstall-repair-and-update-in-windows-7

Then I followed this link to remove the wmware manually : 
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1308

Now when I go to control panel/programs and features, there is no wmware in the list, but when I want to install older version of wmware (v8.02), I get this error: the newer version is installed on the system with a uninstall button.
When I click on this button I receive this error: Bad Arguments for :C\ProgramData\VMware\VMware/Workstation\Uninstaller\unistall.exe

I tried also to install v8.04 again, but I got the same error.

I researched the whole day on it, but still no success. I appreciate for any help.
