Installing claude co work on my computer

I'm looking for someone who can help me properly set up Claude Desktop (Cowork mode) on Windows.

I already installed Claude Desktop and I'm trying to use the Cowork feature that allows Claude to read and write files in a local folder.

However, Cowork keeps failing with a filesystem mount error.

Error message:

"RPC error -1: failed to ensure virtiofs mount: Plan9 mount failed: bad address"

What I need help with:

• Diagnose why Claude Cowork cannot mount a local folder on my Windows machine
• Fix the configuration so Cowork can successfully access a local directory
• Ensure Claude can read and write files in that folder
• Verify the setup is working correctly

My system:

• Windows 11
• Claude Desktop installed
• Paid Claude plan (Cowork enabled)
• Local folder with markdown context files

This should be a quick troubleshooting session for someone who knows the system.

Please reply only if you've worked with Claude Desktop / Cowork before

Contract duration of less than 1 month.

Mandatory skills:

Claude, LLM Prompt Engineering
