Hi. I upgraded my 98 system to XP, and now my McAfee is not working. I need to uninstall and reinstall it, but I lost the old CD, so I bought a new version - but apparently for some reason, I need the original CD to run an uninstall first. This is a pain. Is there some sort of registry thing that I can do to make the new version / WindowsXP think that it's no longer installed so I can install the new version?
