What's Wrong?

Description

After installing @anthropic-ai/claude-code@2.1.113, I encountered a Windows compatibility error when running the claude command.

The error message indicates that the executable is not compatible with my Windows version.

Version 2.1.112 works correctly, but after updating (or opening a new terminal), it seems to switch to the newer version and fails.

What Should Happen?

The CLI should run normally on Windows (same as version 2.1.112).

Error Messages/Logs

Steps to Reproduce

  1. Install version 2.1.112:

```bash
npm install -g @anthropic-ai/claude-code@2.1.112

  1. Run claude → works fine
  2. Open a new terminal or update to 2.1.113

Yes, this worked in a previous version

Terminal/Shell

Additional Information

It appears that the claude.exe binary included in version 2.1.113 may not be compatible with this Windows environment.

Possible causes might include:

Incorrect build target (e.g., architecture mismatch)
Packaging or bundling issue
Dependency/runtime mismatch

Since version 2.1.112 works correctly under the same environment, this seems to be a regression introduced in 2.1.113.

Please let me know if I can provide additional logs or help test a fix.
