Add or Remove programs

By ltchang ·
My OS is XP-Home. I try to remove a program through Control Panel-Add/Remove, but it would not allow (program does not have uninstall), the pop up showing: "An installation support file could not be installed. The system cannot find the file specified."
Is there any way to remove this file.

Chances are it will not uninstall because all of the original files are not there. If you are just tired of seeing the entry in the Add/Remove programs list you can remove it in the registry. Go to:


One of the keys inside the uninstall key will be the one for your program. Delete the key and you will no longer see that entry in Add/Remove programs.

Some Ad and Spyware removers can remove DLLs and or program files. Removal of said files can "break" the ability for windows to uninstall the program but leaving the entry in the registry.

If you want to delete this program the best and easiest option will be to reinstall it then use the Delete Option if one is available on the Install program. Failing that you can just reinstall the program and then use the Add/Remove box in the Control Pannel to un-install the program. What generally causes this problem is that either a Spy Ware program has removed a file or you have allowed Shared Files to be deleted on an un-install which has removed a necessary file for this program to un-install.

On any un-install if given the option always chose to leave Shared Files in place as they can cause other programs to stop working if they are removed.

Many thanks. This is a better and safer way to remove an unwanted program.
