I agree. But I think it says "the software MAY...." The "may" refers
to the software that is included in Ultimate. The problem being that
your disk won't have the 64bit software on it, does it? As others have
said, I guess that if you can get the right disk and your serial works,
then probably give it a shot! Hell, I just popped out $140 for WinXP
pro yesterday after finally giving up on Vista. As far as I'm
concerned, MS owes me money & time for the technological mishap known as
Vista. I'd try any method to get more out of MS after going through
this debacle.

cheers
