Don't know there is any difference between the GX Developer for the A & Q Series and the FX series, but I have been running GX Developer for the A & Q on my XP laptop for sometime now with no problem.
I had GX-Developer on two different laptops both running WindowsXP Professional and had no problems. Sorry, I can't remember the software version, it's been at least a couple of years since I've used that software.
