The computer is running Windows XP Professional SP3. When I go into Control Panel>Add or Remove Programs, there are no options showing for "Remove" or "Change" program. I took this issue up in the Infection forum and tried to get it resolved there.
However I couldn't fix the problem. After doing a registry backup, I performed tweak #337 in Kelly's Korner, as instructed, and then attempted a System File Checker "scannow" repair. The problem still exists. Anybody got any ideas?
