Problem: You want to remove a program that doesn’t show up in Windows’ Add/Remove Program feature (or you have used this feature and the program has not been completely removed).
Solution: Remove the program manually.
Here’s how:
1. Create restore point on your computer.
2. As you will be editing the registry, back-up the registry. Click here to learn how.
3. Because the following steps may impact other applications on your computer, I recommend backing up your entire computer but, that said, I have used this procedure several times with no problems.
4. Find the directory for the application (typically under c:\program files) and delete the directory.
5. Open RegEdit (type regedit in the Run box in XP or Vista or type regedit in the Vista search box).
