Chrome integration is unavailable in the Codex desktop app on Windows.

Observed:

• Chrome plugin is not shown in Plugins.
• Computer Use plugin is unavailable in Settings.
• Settings > Browser says Google Chrome is configured under Computer Use settings.
• Settings > Computer Use says Computer Use plugin is unavailable.
• I restarted Codex and Chrome multiple times, but the issue did not resolve.

Diagnostics:
Native host manifest is missing:
C:\Users\yokot\AppData\Local\OpenAI\extension\com.openai.codexextension.json

Native host registry key is missing:
HKCU\Software\Google\Chrome\NativeMessagingHosts\com.openai.codexextension

Chrome is installed and running.

Expected:
Chrome / Computer Use should be available, or the Codex app should provide a clear setup or repair path.

Actual:
Chrome plugin is not shown, Computer Use is unavailable, and there is no reinstall/repair button in Settings.

What steps can reproduce the bug?

1. Open Codex desktop app on Windows.
2. Open Settings.
3. Go to Settings > Browser.
4. The screen says Google Chrome is configured under Computer Use settings.
5. Go to Settings > Computer Use.
6. The screen says Computer Use plugin is unavailable.
7. Go back to the main app and open Plugins.
8. Search for Chrome.
9. Chrome plugin is not shown.
10. Restart Codex and Chrome.
11. Repeat the same checks.

Result: Chrome / Computer Use is still unavailable.

What is the expected behavior?

Chrome / Computer Use should be available in the Codex desktop app, or the app should provide a clear setup, repair, or reinstall path for the Chrome integration.
