What issue are you seeing?

Computer Use is unavailable in my Codex Desktop app on Windows.

In Settings > Computer Use, the page shows:
"Computer Use plugin is unavailable"

Also, when I type @ in the composer, I cannot find @computer or @电脑. I used to be able to use Computer Use before, but now the entry is missing and the plugin cannot be installed or enabled.

I would like to know whether this is caused by my account entitlement, subscription, workspace policy, region availability, or a client-side plugin issue.

What steps can reproduce the bug?

Steps to reproduce:

1. Open Codex Desktop on Windows.
2. Go to Settings > Computer Use.
3. The page shows "Computer Use plugin is unavailable".
4. Go back to a thread and type @ in the composer.
5. @computer / @电脑 does not appear in the app list.

Expected behavior:
Computer Use should be available or there should be an Install button in Settings > Computer Use. @computer should also appear in the composer when typing @.

Actual behavior:
Computer Use is unavailable, and @computer / @电脑 is missing.

What is the expected behavior?
