Trying to install XP Pro upgrade on newer version of XP Home (SP 3
is removed but still showing in system info). I get the new/old
mismatch message.
There is no such thing as a "Newer version of XP Home".
There is Windows XP Home installed with Service Pack 1a, 2 or 3. Perhaps
that is what you are trying to say. You have Windows XP Home Edition
installed with Service Pack 2 and when you try to utilize your Windows XP
Professional CD (assuming Retail since and OEM copy will not perform an
upgrade) to upgrade Windows XP Home Edition - it gives you a message about
the installed version being newer.
Seeing as how you can actually see that message when it comes up - it would
be good if you copied it verbatim when ever you are asking about it. ;-)
Integrate (some call it slipstreaming) SP3 into your Windows XP Professional
CD. This will require the IT Professional version of SP3, a working
computer (preferably with Windows XP on it) with a CD writer and a blank CD
(as well as your original Windows XP Professional CD.)
Once you create the integrated Windows XP Professional with SP3 CD - you can
use the new CD to upgrade any service pack level of Windows XP Home (granted
again that it is a retail version of XP professional, not an OEM.)
