If you have an XP Pro tag, that means it was factory installed with XP Pro. That key will only work in the OEM version of XP supplied by the manufacturer (and not with a retail XP disc).
It'll install, but an OEM key (like the one on the tag) will not authorize a retail copy of XP; after 30 days, you'll get locked out. If you used the retail key, you have nothing to worry about (unless, of course, it's registered to another computer).

Are you saying the message says "not valid"? If so then the key code you're typing in is incorrect. Are you sure you are typing it in right?
