[BUG] VS Code extension installation fails with 'End of central directory record signature not found' on /status

I found the same issue. my claude-code.vsix file is empty.

Same issue. Was fine until a day ago.

same issue. Mac OS too. claude-code.vsix is empty

Also experiencing this issue on Windows with Cursor IDE. Getting the same 'End of central directory record signature not found' error. This appears to be causing downstream file path resolution issues - I'm getting errors like:
Error: cannot open _claude_fs_right:c%3A%5CUsers%5Cgrant%5CDocuments%5CNinjaTrader%208%5Cbin%5CCustom%5CStrategies%5CExportRenkoBars.cs
This suggests the corrupted extension installation is breaking Claude Code's file system integration entirely. I have separate installations for WSL and Windows - WSL works fine, but Windows fails with both the extension installation error and these file path resolution issues.

Windows: Node.js v24.4.0 (standard installation)
WSL: Node.js v20.19.3
Issue occurs on Windows but not WSL

I have the same issue.

Here is the relevant /status info:

    Please restart your IDE and try again.

Note, restarting the IDE as advised in the error message does nothing.

Here's how I resolved it.

1. Downloaded the vsix file from VS Code extension manager (click gear icon next to auto update).
2. Renamed the file to claude-code.vsix
3. Copied it into the node_modules/.../claude-code/vendor directory overwriting the 0 byte file.
4. Restarted VS Code.

Duplicate of #3574?

I have the same issue on Mac, ~/.nvm/versions/node/v22.15.0/lib/node_modules/@anthropic-ai/claude-code/vendor/claude-code.vsix is empty and CC /status shows extension failure:

I already tried restarting Cursor and reinstalling Claude Code but I am still seeing the issue. FWIW I am using AWS Bedrock not Anthropic API like OP

@PlymouthRock nailed it.
Note: If you are using Cursor, the option to install VSIX won't be there. You'll need to open up VS Code

This fix work for me when running using wsl and starting code form command line. But not from Windows VS Code. If I start claude code from a command prompt and /ide there is the option to select the VS Code IDE which suggests it has connected by Nodejs crashes when it tries to show a file diff.

can someone explain in detail which specific vsix file

Facing the same issue, surprised how it is not fixed yet.

Looks like 1.0.54 resolves the issue. I've installed and tested it. It's listed as next in npm so it's not getting updated on claude update. Had to explicitly install it:

npm install -g @anthropic-ai/claude-code@1.0.54

This should be fixed in the upcoming release.
