If the Microsoft Store / winget download path is the blocker, this unofficial mirror may help:

https://github.com/Wangnov/codex-app-mirror

It mirrors the official Codex desktop installers into GitHub Releases. For Windows, it resolves the current official MSIX from Microsoft Store ProductId 9PLM9XGG6VKS and publishes it with checksums and a release manifest.

Latest Windows MSIX:
https://codexapp.agentsmirror.com/latest/win

This is not an official OpenAI installer and does not replace a proper first-party offline/enterprise installer, but it can be useful when you need the official MSIX package and the Store app/winget flow fails.
