Additional Information

1. claude doctor assumes Claude Code was installed via the standalone Windows installer and hardcodes C:\Program

Files\ClaudeCode\ as the expected path

1. When installed via npm/nvm, that directory doesn't exist
2. Instead of detecting this and printing something like "not installed via standalone installer, skipping

auto-updater check", it segfaults

That's a clear bug — a missing directory should never cause a crash. It should be handled gracefully.

You can report it at https://github.com/anthropics/claude-code/issues with these details:

• Claude Code version: 2.1.119
• Install method: npm via nvm (/c/nvm4w/nodejs/node_modules/@anthropic-ai/claude-code/)
• OS: Windows 11 Pro (arm64)
• Repro: claude doctor → exit code 139 (segfault)
• Root cause: C:\Program Files\ClaudeCode\ does not exist (npm install, not standalone installer)
