Codex DMG -> Windows

This repository provides a Windows-only runner that extracts the macOS Codex DMG and runs the Electron app on Windows. It unpacks app.asar, swaps mac-only native modules for Windows builds, and launches the app with a compatible Electron runtime. It does not ship OpenAI binaries or assets; you must supply your own DMG and install the Codex CLI.

Requirements

• Windows 10/11
• Node.js
• 7-Zip (7z in PATH)
• If 7-Zip is not installed, the runner will try winget or download a portable copy
• Codex CLI installed (npm i -g @openai/codex)

Quick Start

1. Place your DMG in the repo root (default name Codex.dmg).
2. Run:

.\scripts\run.ps1

Or explicitly:

.\scripts\run.ps1 -DmgPath .\Codex.dmg

Or use the shortcut launcher:

run.cmd

The script will:

• Extract the DMG to work/
• Build a Windows-ready app directory
• Auto-detect codex.exe
• Launch Codex

Notes

• This is not an official OpenAI project.
• Do not redistribute OpenAI app binaries or DMG files.
• The Electron version is read from the app's package.json to keep ABI compatibility.
