    Dear TCL'ers,

    how may I find out, if my 32 bit wish is running on a 64 or 32 bit
    Windows OS?

    What I found by tcl_platform and platform::identify is, that a 32 bit
    system is presented.

    Is there any trick ? TWAPI ?

    If "C:\Program Files (x86)" exists -> 64 bit ?


    This is IMHO not guaranteed to exist. But you can look for the WOW64
    folder. My Windows is not running currently, but IIRC then you look into
    C:\Windows (there is some %% magic thing for the correct path) and then
    you'll see if the WOW-Folder exists

    https://en.wikipedia.org/wiki/WoW64

    If that doesn't work, you could compile a small program for 64bit (hello
    World) and try to execute it.

    I take it that there isn't a program like 'uname -m' available under MS-Windows? That would be the goto command I would use under any flavor of Linux (also works on MacOSX!).

    Look at the contents of ::tcl_platform !!!!!

    This is IMHO not guaranteed to exist. But you can look for the WOW64
    folder. My Windows is not running currently, but IIRC then you look into >>> C:\Windows (there is some %% magic thing for the correct path) and then
    you'll see if the WOW-Folder exists

    I'm not sure this answers the question Harald has. When you compile a 32
    bit Tclsh and run it under Win64, tcl_platform still shows everything
    for 32 bit - or not? Harald wants to know if the 32bit binary runs on a
    native 32 bit Windows or via WoW64 on Windows64.
