It is what compiler switches they receive when converted from source-code to executable-code:

  • Windows: (intel-compatible 32-bit) this is the default
    (will execute on both 32-bit & 64-bit Windows using x86 cpu, but only with max 32-bit-wide instructions)
    (therefore 64-bit win has to run in compat mode)
  • x86_64: (intel-compatible 64-bit) this compiled with the 64-bit extensions enabled
    (it cannot be used on 32-bit cpu)
    (certain code that can take advantage of the 64-bit-wide code should run faster)

As your Windows is x64 then use the 64-bit LO release.
