Ok, Im running Windows XP Home addition. Randomly some of my big programs stopped working, saying they're not installed properly. But to reinstall them I have to unistall their older versions. But wait, I open up Add/Remove programs window and I cant uninstall any of my programs. The CHANGE/REMOVE button is simply missing. *update* I installed Norton Anti-Virus just last night and there IS a change/remove button for that, but still not for my other programs. WTF? thanks
