Damaged Add/Remove Program List

By arichart ·
I am running Windows 2K and recently uninstalled MDAC 2.0. Ever since, when I try to run the Add/Remove Programs utility, I receive the following error:

An unexpected error occured

Class not registered

res://appwiz.cpl/listbox.htc
Line:225

I have been to the Windows knowledge base and have tried all of their resolutions but with no success. Any ideas? Can I simply reinstall that program?

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:

HKLM\SOFTWARE\MICROSOFT\WINDOWS\CURRENT VERSION\Uninstall

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.

At this point, no programs will uninstall. Not looking at a specific program but the overall problem that was mentioned. Thanks anyway.
