OpenCode v2.2.7 for Older CPUs: Updated Unofficial Node.js Build (Windows x64)

Update: the Node.js build of OpenCode for older CPUs is now on v2.2.7.

If you missed the first post: the official Windows binary is compiled with Bun, and Bun refuses to start on CPUs without SSE4.2:

this CPU is missing SSE4.2 support, which Bun requires

This build packages OpenCode as a Node.js executable, so that check never runs. Nothing to install, just extract and run.

What changed

• Rebuilt from the official v2.2.7 tag(commit fedc6f2)

Upgrade

1. Remove any old version and cache first
2. Download the new zip from the Releases page.
3. Extract it to a new folder, for example C:\opencode-2.2.7.
4. Run:

cd /d C:\opencode-2.2.7\cli-node-windows-x64
OpenCode.bat

If you added the old folder to your PATH, point it to the new one, then open a new Command Prompt.

Note

• It's an unofficial build, not affiliated with the OpenCode project.

If it doesn't start on your machine, open an issue with your CPU model, Windows version, and the full error text.
