Several readers wrote in to expand on my original reply in "Where’s the Uninstall Hidden?" ( http://langa.com/newsletters/2005/2005-01-24.htm#9 ) by referring to the free "Windows Installer CleanUp Utility" from Microsoft. ( http://support.microsoft.com/default.aspx?scid=kb;en-us;290301 )
In prepping this newsletter, I downloaded and ran the Cleanup tool just to make sure it worked— not trying to correct any problem— but the tool found two unreadable remnant installer files that I didn’t even know where in there. I removed them; and now they can’t cause any trouble.
I hadn’t thought of it before, but it might be a good idea to run the "Windows Installer CleanUp Utility" once or twice a year, just to see if there’s anything weird accumulating on your system.
Thanks to all who suggested this tool!...
