What issue are you seeing?

In Codex Desktop for Windows, the Workspace Dependencies “Diagnose” and “Reinstall” buttons are disabled / not clickable.

I installed Codex Desktop today and restarted the app, but the buttons are still disabled.

Logs repeatedly show:

unsupported feature enablement workspace_dependencies

The related request is:

experimentalFeature/enablement/set

The error message says that the currently supported features are:

apps, memories, plugins, remote_control, tool_search, tool_suggest, tool_call_mcp_elicitation

but workspace_dependencies is not included.

I also verified that the local runtime dependencies can work when placed manually, but Codex still reports:

No bundled workspace runtime dependencies are configured yet.

This looks like Codex Desktop is trying to use the workspace_dependencies feature, but the app-server does not accept that feature enablement.

What steps can reproduce the bug?

1. Install Codex Desktop for Windows.
2. Launch Codex Desktop.
3. Open a workspace.
4. Go to the Workspace Dependencies section.
5. Try to click “Diagnose” or “Reinstall”.
6. The buttons are disabled / not clickable.
7. Check the Codex Desktop logs.
8. The logs show unsupported feature enablement workspace_dependencies for experimentalFeature/enablement/set.

What is the expected behavior?

The Workspace Dependencies “Diagnose” and “Reinstall” buttons should be enabled when the feature is available.

Clicking “Diagnose” should check the bundled workspace runtime dependencies and report their status.

Clicking “Reinstall” should reinstall or repair the bundled workspace runtime dependencies.

Codex Desktop and the app-server should agree on whether the workspace_dependencies feature is supported, so the UI does not expose disabled or unusable controls.

Additional information

I previously saw a deprecated config warning:

[features].codex_hooks is deprecated. Use [features].hooks instead.

I fixed it by changing the config to:

[features].hooks = true

That warning disappeared after restarting Codex Desktop.

However, the Workspace Dependencies issue remains.

Codex CLI version:

codex-cli 0.129.0-alpha.15

The Codex App version appears to be:

26.506.2212.0

I also manually placed the primary runtime under:

C:\Users\<user>\.cache\codex-runtimes\codex-primary-runtime

Node and Python inside that runtime worked when tested manually, but Codex still reported:

No bundled workspace runtime dependencies are configured yet.
