HI Deborah,
Alot of people have some confusion between Windows XP (an operating system)
and Office XP ( which are office tools). Both of these programs come in a
standard or home edition and both have a professional edition.
So.. you can indeed run Office XP Professional on your Windows XP home, just
as you can run your Office Standard on your Windows XP Professional. Your
Windows XP regardless of its type, is what runs your Office Suite, and will
run either version of Office XP.
If you are trying to put on two operating systems (Windows Xp) you would
have to partition your drive...but why bother. If you have Windows XP Pro
then it has more features then home and I would use that. Same is true with
Office.
So my advice is to really look at your disk your installing, if you trying
to install Office on Windows, your fine.
I hope this helps clear things up a bit
