I use tune up 2004 to uninstall all of my programs works good. I've installed and uninstalled mcaffe about 3 or 4 times using add/remove program list and it worked fine for me. I'm currently using mcaffe and I think my comp is slower with it but I'm not sure. did you comp seem slower when you installed it?
