To night I had problems with uninstalling VMware Tools in a VM after updating to the latest ESX release.

The uninstaller kept asking me to insert the “VMWare Tools” disk and click OK”.
In the popup window there is pull-down field labeled “Use Source” and in this field is the number one (“1″).

If I tried to browse to the the “VMware Tools.msi” it returns an error: “The file ‘X:\VMware Tools.msi’ is not a valid installation package for the product VMware Tools…”

The solution I used to get around this problem was simply:

  1. Open the registry
  2. Locate “[HKEY_CURRENT_USER\Software\Microsoft\Installer\Products\8E24D35BB278E034284D0860A513CF1E” and delete it.
    (If you don’t want to delete it, just rename it or make a backup first)
  3. Run the VMware Tools installation again.

And wola it nor works :-)
