C:\Windows\System32\appwiz.cpl is not a valid Win32 application

[Marceepoo]

proc = subprocess.Popen(r"C:\Windows\System32\appwiz.cpl")

generates the following error:
OSError: [WinError 193] %1 is not a valid Win32 application

Any suggestions about how to fix this, and/or where to learn more would be appreciated.

Thanks,

The error message is clear.
Windows OS cannot find the application

[Marceepoo]

Thank you, Larz60+, for responding.

I do not understand why Windows OS cannot find the application when I run my python command:

proc = subprocess.Popen(r"C:\Windows\System32\appwiz.cpl")

If I open a "Command Prompt" window on my Windows 10 Professional system, by clicking the icon that runs:

"C:\WINDOWS\system32\cmd.exe"

... and I run the command line "appwiz.cpl":
Windows runs the command successfully, and
The command effectively opens a program window entitled: "Control Panel\All Control Panel Items\Programs and Features"

What do I need to do when I run subprocess so that the Windows OS can find the application

"C:\WINDOWS\system32\cmd.exe"

?

Thank you again for taking the time to reply and help me. Much appreciated.

try

subprocess.run(['appwiz.cpl'], shell=Tue)

or

subprocess.run(['contol', 'appwiz.cpl'], shell=Tue)

[snippsat]

Set shell=True when a call command that's not in a list.

import subprocess

proc = subprocess.Popen(r"C:\Windows\System32\appwiz.cpl", shell=True)

Alternative not using shell=True,look upon as safer way.

import subprocess

proc = subprocess.run(['control', "appwiz.cpl"])

Edit:did not see post from @buran,as i did a test of this when posted.

I was not able to successfully run it without shell=True. I get the same error as OP

This work fine for me Python 3.7 Win-10,tested on couple of Pc's.

import subprocess

proc = subprocess.run(['control', "appwiz.cpl"])

[Marceepoo]

Buran's code worked for me:

import subprocess

proc = subprocess.run(['control', "appwiz.cpl"])

Thank you!

Buran's code worked for me

It was @snippsat's code, but good that your problem is solved.
