But if you do face a situation where you find that you are unable to uninstall, repair, or update some software, even when you have not deleted any files from the cache, it may be possible that Windows Installer cache folder may have been compromised or corrupted. For instance. Windows Installer will clean-out the installer cache if ever the owner on the %WINDIR%\Installer directory changes from SYSTEM or Administrators.
If you think of copying the missing installer files from some other computer to this one, it will not help, as the files from the cache are unique for every system.
