Determine if version is 64 bit?

[Dave F.]

Hi

I use both 32 & 64 bit versions of 2012 on separate PC's & have different ARX file for each. How do I test, with VBA, which version I have open? The ACADVER variable returns the same number.

Check PLATFORM variable and
see if it contains x86 substring in there

Did this one a while back:

<snip>

(defun _64Bit-p ()
  ;; © RenderMan, 2011
  ;; Returns T if version is 64Bit
  ;; Example: (if (_64bit-p) "64-Bit" "32-Bit")
  (vl-load-com)
  (if (vl-string-search "64" (getenv "PROCESSOR_ARCHITECTURE"))
    T
    nil))

This thread may be of specific use, given your ARX file requirement.

Hope this helps!
