I'm not 100% sure, and I'm not there to read the box. If the seal is broken, what the hell; its worth a try? My XP home was upgraded from 98,ME and 2000. The XP upgrade "should" reconize your other :dark1: software. Note: if you have two drives, back-up all your good stuff onto the spare drive just in case it re-writes more then just the operating system...unless you don't care.
