Running RO in a limited account of windows XP

[Frogboy]

well setup.exe is checking to make sure your system can handle the RO engine (which most windows based computers can). my guess would be that the way the computer is set up, it does not save certain types of file settings. not sure how you'd be able to get permission for that, but with only the information you've given there it's hard to diagnose what is going on.
