Hi Crystal, No, my system isn't 64-bit - it's 32. The drivers and display worked great when I was running Vista. I just had a whole wackload of other problems, which was why I upgraded to 7. The case for switching to Mac as my next system is getting stronger by the day...lol!

If it is, then good luck. Freedom Scientific will not support your display if the manufacturer does not pay fees for the drivers. Crystal
