I've set up multiple profiles on XP Home for the members of my family. I installed Star Wars: Knights of the Old Republic using my administrator profile, but can't get it to work on the other, limited profiles. It doesn't appear in the start menu, but is in Program Files. When I open it in a limited profile and start a game, it stops partway through loading. What can I do to fix it? Do I need to install it for each profile.
