Re: Installing 64bit Ultimate edition over 32bit Windows XP Profes
You will have to do a clean install of Ultimate 64, but you are entitled to
do it with XP86 as the qualifying OS. Just remember that all drivers must
be 64-bit and are not as available as 32-bit drivers and some programs will
not run on 64-bit. Make sure drivers are available for your hardware, and
unfortunately there is no way to tell in advance if there will be a problem
with your programs.
