`Verify Windows installer execution` failed twice in a row on the v0.5.0
tag, both times at the same assertion:
Elevated default-mode reinstall without CLR expected process exit
code 20, received 22.
20 and 22 are different answers to "why did setup stop". 20 is legacy
recovery refusing to continue; 22 is "a matching process is running". The
stage breaks the CLR on purpose so the installer cannot run PowerShell,
which is exactly when CcHahaFindInstallProcess degrades from resolving
paths to matching bare image names -- `Claude Code Haha.exe`, the three
`claude-sidecar*` names, `OpenConsole.exe`, `winpty-agent.exe`, `rg.exe`.
Any process on the runner carrying one of those names answers for the
stage, whoever started it.
The stage before it expects 22, so a stray match there is indistinguishable
from a pass; the stage after it expects 20, so the same stray match is a
failure. That asymmetry is why this reads as "one flaky assertion" rather
than "the whole no-CLR group is unguarded".
This does not fix the installer, because the installer is not wrong:
refusing to delete user data when it cannot confirm what is running is the
intended fail-closed behaviour, and neither installer.nsh nor this script
changed between v0.4.11 (green) and v0.5.0 (red). What changed is what was
running on the runner. So the script now controls that instead of assuming
it:
- Both stages that expect 20 first clear any process matching the same
name list. `WaitForExit` only covers the PIDs this script started; the
fallback matches names, so it also sees leftovers from earlier steps of
this job -- the compiled-sidecar smoke starts 20 sidecars -- and any
child a probe spawned.
- Clearing warns instead of throwing when something survives. A survivor
is runner-owned and out of reach, and failing there would replace the
stage's own failure with a less informative one.
- A mismatched exit code now prints every matching process with PID and
path, and a baseline is printed before the first install. Between those
two, a future failure says whether the runner was dirty or the installer
regressed, which this run had no way to answer.
The name list is duplicated from installer.nsh by necessity -- NSIS
compile-time state is not readable from PowerShell -- and is commented on
both sides to be kept in sync.
Not verified locally: this needs Windows and an ephemeral runner (the
script refuses to run unless CI=true, since it mutates installer registry
state). Reviewed for Windows PowerShell 5.1, which is what the workflow
invokes: no pwsh-only syntax, and the file is kept pure ASCII as it was,
so 5.1 cannot mis-decode it.
Claude Code Haha
A Claude Code build repaired from the source leaked from Anthropic's npm registry on 2026-03-31. Claude Code Haha is now primarily a desktop Claude Code workspace for macOS, Windows, and Linux: sessions, projects, branch / Worktree launch, right-side file changes, code diffs, permission review, provider setup, Computer Use, H5 remote access, IM integration, and scheduled tasks in one app.

Desktop Preview
The Claude Code Haha desktop app brings sessions, multi-project navigation, branch / Worktree controls, right-side file changes, code diffs, permission review, provider setup, and remote access into one graphical workspace for daily development flows beyond the terminal.

Install the Desktop App
- Download the macOS / Windows / Linux desktop installer from Releases.
- On first launch, configure your model provider, API key, and default model in Settings.
- Public macOS releases require signing and notarization. Draft or unsigned temporary builds may still need one-time manual approval. Unsigned Windows installers may show SmartScreen; click "More info" -> "Run anyway". See the desktop installation guide.
Run the CLI from Source
For users who want to debug the underlying CLI, server, or local development flow:
bun install
cp .env.example .env
./bin/claude-haha
See environment variables and global usage for more configuration options.
Desktop Highlights
- Multi-session workspace: tabs, project switching, terminal entry, and session history in one place.
- Branch / Worktree launch: choose a repository branch and decide whether to use the current working tree or an isolated Worktree.
- Right-side file changes: review changed files, added/removed lines, and current workspace state while chatting.
- Visual code changes: inspect edits, file writes, and diffs directly in the desktop app.
- Permission review: approve risky commands, tool calls, and model follow-up questions in the GUI.
- Multi-provider setup: configure Anthropic-compatible APIs, third-party models, WebSearch fallback, and local options.
- Skill Marketplace: discover, preview, install, and manage third-party skills from ClawHub / SkillHub in the desktop app.
- Session Activity Panel: review tasks, background tasks, SubAgents, team activity, and sources in one side panel.
- Computer Use: let the agent take screenshots, click, type, and control desktop apps after authorization.
- H5 remote access: open the current desktop session from a phone or another device with a one-time token.
- IM integration: chat, switch projects, and approve actions through Telegram / Feishu / WeChat / DingTalk.
- Scheduled tasks and usage stats: create planned tasks and track local token usage trends.
