Hi, I did a Windows Repair using the original Dell XP CD that came with the computer. Well during this process an error message popped up stating: Software Installation has not passed Windows Logo testing to verify its compatibility. This software will not be installed. Contact your system administrator. So I clicked to continue. I got back onto Windows desktop and a few errors popped up. One of which is McAfee. I can't get McAfee to work at all. The icons are there and when I clicked them nothing comes up. I tried to uninstall McAfee and it won't even do it. It just hangs there during the uninstall. So I put the Dell cd in to install it that way. That didn't work. I went and downloaded AVG free so I would be secure. I would love to know how to uninstall and reinstall McAfee. This is not my computer it is my Uncle's. If it was my choice I would stick with AVG free. Also when you do a Windows Repair you lose the Service Pack 2. So I tried to install that and it failed halfway thru. I used the SP2 cd I had and also tried it off Windows Update. No luck. I tried doing it in safe mode still no luck. Any solutions to fix these problems? I wanna exhaust all possibilities before I go with the format the drive and do a fresh XP install. Thanks.
