If you've installed a new programme in W7 and can't uninstall it the usual way, you may wish to try the "Windows Installer CleanUp Utility". You can download it here: Description of the Windows Installer CleanUp Utility You'll need to run the installer file you download as administrator. Once installed, go your Program Files folder>Windows Installer Cleanup> find the "msicuu.exe" file in the folder [right click on the msicuu.exe file & under the 'compatibility' tab set it to run with Vista compatibility & as Administrator]. I also advise doing the same for the msizap.exe file under its 'compatibility' tab. Once you've altered both .exe compatibility settings you only run the msicuu.exe file, choose the programme that needs removing and click on 'Remove'. Also, I advise reading the "Read Me" file before running the utility. This can also be found in the Program Files>Windows Installer Cleanup folder.
