Why %processor_architecture% always returns x86 instead of AMD64

Question

I am trying to retrieve the environment variable to detect whether the system is 32 or 64 bit. But on 64 bit server the environment variable %processor_architecture%

Answer 1

Are you actually running a 64-bit version of Windows? If you are running 32-bit Windows on a 64-bit-capable CPU, you will still get x86.
