The Codex App fails to launch on Windows and throws an Electron error. It seems the app cannot handle the space within the Program Files directory path, cutting it off at C:\Program

Also encountered this after Codex finished a response.

I’m seeing the same issue on Codex App version 26.527.31326.

In my case, this happens specifically after clicking a Codex Windows notification. The main app still works, but the notification click triggers the Electron error dialog.

The error contains:

Unable to find Electron app at:
C:\Program Files\WindowsApps\OpenAI.Codex_26.527...\type=click&tag=...

Cannot find module:
C:\Program Files\WindowsApps\OpenAI.Codex_26.527...\type=click&tag=...

After turning off Codex notifications in Windows Settings, I have not seen the error dialog appear again so far.

Same issue for me with 26.527.31326. I haven't been able to use the plugins I need since I downloaded this thing almost a week ago.
