What platform is your computer?

Windows x64 + WSL Chrome on Windows Codex desktop app Chrome extension v1.1.4

What issue are you seeing?

The Codex Chrome plugin appears connected/installed in the Codex app, but the Chrome extension popup always shows:

Disconnected Use the Chrome plugin in Codex to connect. Version v1.1.4

Codex opens Chrome and asks me to install the extension. The extension is installed, but it never connects. Reinstalling/reconnecting the Chrome plugin from Codex does not fix it.

Diagnostics:

• Chrome extension ID: hehggadaopoacecdllhhajmbjkdcmajg
• Chrome extension version: v1.1.4
• Plugin package seen locally: chrome@openai-bundled 0.1.7
• The native host is not registered on Windows.

Missing manifest: C:\Users\rodri\AppData\Local\OpenAI\extension\com.openai.codexextension.json

Missing registry key: HKCU\Software\Google\Chrome\NativeMessagingHosts\com.openai.codexextension

Official checker output: Windows native host registry key does not exist; Native host manifest does not exist.

There is no visible error in the Codex app. It just keeps opening Chrome/install flow, while the Chrome extension remains Disconnected.

Expected: Connecting/reconnecting the Chrome plugin from Codex should create the native host manifest and Windows registry key, then the Chrome extension should show connected.

Actual: The Chrome extension stays Disconnected forever.

What steps can reproduce the bug?

1. On Windows, install/connect the Chrome plugin from the Codex desktop app.
2. Codex opens Chrome and prompts to install the Codex Chrome Extension.
3. Install the extension.
4. Click the Codex Chrome Extension icon in Chrome.

Result: The extension popup shows:

Disconnected Use the Chrome plugin in Codex to connect. Version v1.1.4

1. Disconnect/reconnect or reinstall the Chrome plugin from the Codex app.
2. Repeat the Chrome extension install/connect flow.

Result remains the same: the Chrome extension stays Disconnected.

Diagnostics run locally:

• Chrome extension ID: hehggadaopoacecdllhhajmbjkdcmajg
• Chrome extension version: v1.1.4
• Plugin package: chrome@openai-bundled 0.1.7
• Native host manifest is missing: C:\Users\rodri\AppData\Local\OpenAI\extension\com.openai.codexextension.json
• Windows registry key is missing: HKCU\Software\Google\Chrome\NativeMessagingHosts\com.openai.codexextension

Official checker output: Windows native host registry key does not exist; Native host manifest does not exist.

What is the expected behavior?

After connecting the Chrome plugin from the Codex desktop app, Codex should create/register the native messaging host on Windows.

Expected files/registry:

• C:\Users\rodri\AppData\Local\OpenAI\extension\com.openai.codexextension.json
• HKCU\Software\Google\Chrome\NativeMessagingHosts\com.openai.codexextension

Then the Chrome extension should connect successfully and no longer show "Disconnected".

Additional information

There is no visible error in the Codex app. The app keeps opening Chrome / extension install flow, but the extension remains disconnected.

Reinstalling the Chrome extension and reconnecting the plugin from Codex did not fix it.

This is blocking use of the Chrome plugin in Codex on Windows.
