Hi Matt,

I think I figured out what Sergey meant in his comment - if OS() >='6' then the OS would have the function, that checks for is it 64 or 32, otherwise this function is not present. You still need to use that Windows API, but you would not need to add extra checks.

BTW, Sergey updated his code and it now clearly shows what he meant by OS() check.
