You want to use WSL for this, obviously. Pretty sure it says windows not support.

If you are using WSL - then make sure you have the browser in the PATH. A friend of mine had the same issue.

Encountering a similar issue with windows returns Error logging in: program not found

> codex --version
codex-cli 0.20.0

@LuciferMornens well there is a windows exe in the latest release 🤷‍♂️

Workaround that worked for me

If you’re running into this issue, try the following steps:

  1. Install version @openai/codex@0.16.0

``bash
npm install @openai/codex@0.16.0
``

  1. Log in with your account

``bash
codex
``

  1. Upgrade back to the latest version

``bash
npm install @openai/codex@latest
``

This isn’t a permanent fix, but it got things working for me earlier today.

After doing this, my session shows:

👤 Account
 • Signed in with ChatGPT
 • Login:
 • Using API key. Run `codex login` to use ChatGPT plan

So if using the step listed in this reply, it might use API instead of the plan, is anyone using this meet this issue?

Still having the issue 'login_with_chatgpt subprocess failed'

Same problem Error logging in: login_with_chatgpt subprocess failed:
SOLVED: In the Python installation directory, copy python.exe, paste it in the same directory, and rename the copy to python3.exe

It's the best. It's been solved in a ridiculous and surprising way.
