Gentlemen, thank you. Prob is, I'm here in Derbyshire; daughter in Stockport, and it's run-up-to-xmas time, so best part of a day out of my life ain't practical just now. I'll prob ask her to bring the box down with her when she comes for Santa Special day, and we can get it back to her after Christmas.
Meanwhile, I'll copy and paste the suggestions given.
the "Academic" XP install is probably a volume licence version and neither an OEM or retail disk will work with it.
(Thought someone would say summat like that,
MM; suppose I could buy an XP license if wuss comes to wuss...)
