If you remember about two months ago, I posted about a friend who had a Compaq, and after installing AOL, then installing a different internet which didn't work because of some DLL problems, and you guys told me something about AOL messing up connections and you guys gave me some ways to fix it. Well anyways, my friend tried unsuccessfully to fix it himself, and now he game me his computer, but I have no idea what to do now. Whenever I try to open and program, even Add/Remove and all those programs in the Control Panel, its gives me an error, something like missing C:\Windows\rundll32.exe file. So what can I do now?
