I thought I'd point out that if you want the InfoTip to work, you have to make sure you point to the unregmp2.exe in your install. I don't know why mine's in a different location than Rick's, but mine is in the 'inf' directory, so I had to use the following: InfoTip = "@%%SystemRoot%%\inf\unregmp2.exe,-160" DisplayResource = "%SystemRoot%\inf\unregmp2.exe",4
