Well, if it is on a school computer, I assume that you have your unique user id and pass. It might be that the admin hasn't given permission for installing programs and registry entries might not be entered properly. School comps usually have a program(Ours is Deep Freeze) that erase all changes in the computer upon reeboot. That would explain why it works on a home comp but not a school comp. To see if you have Deep Freeze, hit Shift+Ctrl+Alt+F6 I a dialogue appears, it is installed.
