I have two machines both with xp, one with xp pro and the other home addition. I have six different photo programs including photo shop 6.0 pro and the only software i use to edit is adobe photodeluxe 2.0. yes you can get it to work there are a couple changes you have to make.
Once you install the program, you will have to go to your virtual memory settings in control panel/system/advanced/performancesettings/advanced and change the virtual memory settings, i currently have mine set at 4000 and 4086. That should get you into the program, try it and see if it works.
Once you open a photo that is on your computer you may encounter a scratch disk error. go up to file, prefrence and increase your scratch disk number. if you have a partitioned drive use that as the secondary scratch disk, if not just use c: as the primary and none as the secondary. it should work as i've installed it in about five machines running xp...you get a glitch here and there but it beats not having it at all......
