In Batch files, you can easily check for architecture by using the “processor_architecture” variable. x86 versions of windows will have this set to “x86″, and x64 versions “x64″. Heres an easy example:

@echo off
IF %processor_architecture% == AMD64 echo This is a 64-bit version of windows
IF %processor_architecture% == x86 echo this is a 32-bit version of windows.
