Hello. Using Maya 8.5 on Prescision 690, OS XP-Pro, 2 Gig RAM.

I currently run the XP 32 bit OS and plan to install the 64-bit to enable me to build out the RAM capabilities of the computer. I don't recall if my Maya 8.5 which I bought in 2007 was for a 32-bit OS specifically, or if it will run on either OS. Are there different versions of the program for 32-bit or 64-bit operating systems?

Anyone know?

Thanks, T
