Windows FIX : ACP adapter installation fails for both Claude Code and Codex #2407
Closed as not planned
Description
Fix for the following issue: 2343
Install [Git for Windows] (https://git-scm.com/download/win)
then open PowerShell as admin:
install NodeJS:
winget install OpenJS.NodeJS.LTS
update your system's execution policy to allow locally written scripts to run:
Set-ExecutionPolicy RemoteSigned -Scope LocalMachine
then install codex:
npm install -g @openai/codex
and the codex acp:
npm install -g @agentclientprotocol/codex-acp
then install Claude:
npm install -g @anthropic-ai/claude-code
then the claude acp:
npm install -g @agentclientprotocol/claude-agent-acp
re open the Buzz app and it should now find it

This fixed #2401

🤖 Thanks for writing up the manual workaround — it unblocked other reporters while the underlying bugs were open (confirmed working on #2401). Closing this one now because the root causes it worked around are fixed in v0.4.25: the Windows
PATHbug (#2563) and the installer routing bug (#2750), so the manual Git-for-Windows + winget-Node +npm -gsteps are no longer needed on current builds. If a fresh v0.4.25+ install still needs any of these steps, that's a bug — please reopen and say which step was still required.
