What's Wrong?

After running this command to install CC

irm https://claude.ai/install.ps1 | iex

I got

✔ Claude Code successfully installed!

  Version: 2.0.67

  Location: C:\Users\miku\.local\bin\claude.exe


  Next: Run claude --help to get started

⚠ Setup notes:
  • installMethod is native, but claude command not found at C:\Users\miku\.local\bin\claude.exe


✅ Installation complete!

However

• There isn't claude.exe on my device,
• ~/.local/bin is an empty folder,
• And as a consequence, my terminal reported claude is not a valid command.

What Should Happen?

~/.local/bin/claude.exe should exist, as the install script printed "Claude Code successfully installed!".

Additional Information

• Windows 11, 25H2
• Probably not permission problem, because I didn't see obvious permission corruption in my filesystem - I deleted the entire ~/.local folder and the problem persists - the install script recreated ~/.local and many descendants were successfully created except claude.exe
• npm method works
• Running with Administrator privileges does not help
• My case is different from "claude.exe exists, but 0 kb" - mine is "claude.exe was never created".
