hi all just bought another computer it is a amd athlon 64 processor and just wanted to know if i should use the nod program for 64 bit. any advice would be appr.
Only if you install Windows 64 bit version, then you would need to run the 64 bit version of NOD. The processor may support 64 bit, but the software will still be 32 bit only, and that's what's important.
