1. [Bug] Windows: Codex ACP setup reports a current adapter as outdated #2342
Description
I ran into this while setting up the Windows desktop app.
Buzz detected my Codex CLI, but the Codex card kept showing:
ACP adapter detected but outdated — reinstall required.
Pressing Set Up then ended with “Setup failed”.
My environment:
- Windows 11 x64
- Buzz 0.4.21
- Node.js 24.4.1
- Codex CLI 0.144.6
@agentclientprotocol/codex-acp1.1.5
The adapter itself was working:
codex-acp --version
@agentclientprotocol/codex-acp 1.1.5
The issue seems to be the PATH used for the Windows adapter check. Buzz resolves the adapter from %APPDATA%\Buzz\node-tools, but the restricted PATH used to probe it does not include the normal Node.js installation. The npm codex-acp.cmd shim then cannot find node.exe, so the version check fails and Buzz treats the adapter as outdated.
As a workaround, I installed the adapter into %APPDATA%\Buzz\node-tools and copied node.exe from my Node installation into that folder. After restarting Buzz, Codex was detected correctly.
It may help if the Windows probe preserves the normal Node.js PATH, provisions Node for this private tools folder, or invokes the shim with an explicit Node path.

I also noticed another issue on Windows: Git Bash opens in a visible terminal window while navigating between channels or screens in Buzz.
The window is running:
C:\Program Files\Git\bin\bash.exe
It can open repeatedly even when I am only moving around the app. Since Git Bash is needed for shell-based agent work, I expected
it to run silently in the background.
This may be separate from the Codex adapter detection issue, but it could be related to how Buzz starts shell processes on Windows.
