I recently upgrade my computer. Before I had Windows 7 Premium 32Bit and installed PD9 Ultra and it loaded the 32bit system files. Then When I got my new Computer windows 7 Premium 63Bit i7 2600 processor and loaded PD9 Ultra it loaded the 64bit version and all the bells and whistles. The PD9 Ultra when installing install the files needed as per your system specs, be it 32 or 64 bit.
The 64bit has a few more options for the program.
