Add/Remove Programs - Change/Remove Button is Missing!

[themediachick]

Hi all,

I just went to uninstall a program and found that the Change/Remove button is missing for almost all entries in Add/Remove Programs.

Out of curiosity, I just scanned the registry with CCleaner, and most of the programs I have installed showed up as an Uninstaller Reference Issue.

Does anyone know how this could have happened, or what I need to do to fix it?

During the past couple of days I've received some help here for something very minor, which I don't think is related. Here's the link to the thread:

Incidentally, a few hours ago I uninstalled a small program with no problems, so it's just occurred.

Thanks!

P.S. Running Windows XP with all updates.
