What's Wrong?

On Windows ARM 64

Installing Claude Code through either Powershell or Command Prompt says "Installation Successful" but it silently fails and doesn't actually install.

Installing Claude Code through npm works correctly. However, then running claude install to try a native install fails with the error:

✘ Installation failed

Platform win32-arm64 not found in manifest for version 2.1.29

What Should Happen?

Claude Code native should install
