Should be good. I'm on a Mac, OSX, so I can't help. Someone who knows XP might want to know what was in the error message, though.
In the meantime, did you try whatever you do in XP to uninstall/download a fresh copy/ reinstall? You could also try looking in the Installation Windows forum

Sorry I can't help more.
