Try re- installing windows xp. When it's up and running, before installing any programmes, go to "start" "programmes" and "software compatability" follow the instructions untill XP ask you for the programme CD-Disk you want to install. Insert the disk and load the programme. When the programme is loaded, chose the 2000pro compartable option and let xp do the rest.
This action usally works if the programme you want to install is 32bit or less. We must remember xp is a 64bit based operating system.

XP is still a 32-bit OS. I don't believe that Windows has officially released a 64-bit OS to the general public yet. There have been sightings of it in the wild (like the company that I work for, but I didn't get to see it with my own eyes).

Windows XP Pro is not 64 bit it is 32 bit, but...

Windows XP 64bit for Workstations is 64 bit (hence the name, lol)

But as far as I know it is still in evaluation form only. Hope that helps.
