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 ?

Thanks for any idea, I feel quite dump.

Harald

P.S. The background is to open the on screen keyboard from a touch-only application. The 64 bit version at an obscure path must be called on 64
bit versions. The 32 bit version exists but shows an error box:

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.

Hello,

Check out tcl_platform(wordSize). I believe it is 4 for 32-bit and
higher for 64-bit platforms.

Dear all,

thank you for all great propositions.

Yes, tcl_platform and ::platform::identify was my first point.
Unfortunately, they are identical for a 32bit wish running on 32 and 64
bit windows.

But thank you for all the other propositions.
I prefer the twapi solution, as twapi is anyway present.

And I was surprised that even magic Cristian Gollwitzer is caring about
Windows ;-).

Thank you and take care,
Harald

Not an answer to your question, but potentially to your end goal - have you tried just using [auto_execok osk.exe] ? Not extensively tested by any means but returns a suitable result on my current (64-bit Win 7) system.

Mike,
thank you for the suggestion.
Yes, this file is present. If you execute it, you get an error box. "[autoexec_ok start] osk" does not find it and "file exist" returns 0,
even as I can see it in the file explorer.

This experience was the root of the my question.

Thank you all for caring,
Harald

As Harald pointed out, this doesn't work on Windows-10 64bit:

$ cat t.tcl
puts [auto_execok osk.exe]
exec [auto_execok osk.exe]

$ tclsh t.tcl
C:/Windows/system32/osk.exe
couldn't execute "C:\Windows\system32\osk.exe": invalid argument
while executing
"exec [auto_execok osk.exe]"
(file "t.tcl" line 2)

$ uname -a
MINGW64_NT-10.0-19044 serval 3.2.0-340.x86_64 2021-08-02 16:30 UTC x86_64 Msys

Typing 'osk' in a windows cmd shell however works, and

exec cmd /c osk

works, too from tclsh. However, I would bet this does not work on a
32-bit system :-)))
