Is there an easy way to tell if an app is 32 or 64 ?

Probably answered before but can't recall ....

Mayayana probably has some code for this.

I on the other hand, specialize in answers you won't like :-)

This is easy with the Bash shell in Windows 10. You
use the "file" command in Bash. Note that "file.exe" is
also available in GNUWIN32 (runs on Windows), as well
as Cygwin (runs on Windows). And none of those options
is going to make you happy (setting those up, takes work).

A "PE32" is a 32-bit program.

A "PE32+" is a 64-bit program. They seemed a bit timid
when picking a name for that one :-) .
