We used to have a great tool for uninstalling failed installs in XP with the MicroSoft uninstall clean up utility. Since going to Windows 7 this option was no longer available as the tool was not supported with Windows 7. Great News!!! There is now a link to an updated version of the tool that is suited for Windows 7. This utility runs from their website or has options to download for machines not on the internet.
I have tried it a few times with mixed results. Not thrilling, but if there is nothing else left to loose, why not give it a shot?
Here are the links to the new Microsoft cleanup utility:
The Windows Installer Cleanup utility (MSICUU2.exe) has been retired by Microsoft and has been replaced a new utility (this is the download link):
The Microsoft KB article that has more information about this tool can be viewed at http://support.microsoft.com/kb/2438651/.
