What issue are you seeing?

Hello Codex team,

I am having an issue completing the Windows setup in the ChatGPT Desktop app.

When I start the setup, Windows asks for administrator permission. I click Yes, but ChatGPT then shows the following error:

Windows setup was not completed.

I tried clicking Try Windows setup again, but the same issue continues.

I also tried:

Repairing the ChatGPT app from Windows Settings
Closing and reopening ChatGPT
Running ChatGPT as Administrator
Approving the Windows administrator permission prompt

The issue is still not resolved.

What steps can reproduce the bug?

1. Open the ChatGPT Desktop app on Windows.
2. Start the Windows/Codex setup.
3. Click Yes when the administrator permission window appears.
4. The app returns to the setup page.
5. The message “Windows setup was not completed” appears.

What is the expected behavior?
