🛠️ Fix: "Unknown Error Occurred" - Chrome Remote Desktop on Windows

When reinstalling Chrome Remote Desktop or switching Google accounts, you might encounter this vague error:

"An unknown error occurred"

Even after uninstalling everything, this issue may persist due to leftover config files.

✅ Solution: Manually Remove Residual Configuration

1. Uninstall Chrome Remote Desktop Host

   • Go to Control Panel > Programs > Uninstall a program
   • Uninstall Chrome Remote Desktop Host

2. Delete this specific folder (crucial!)

%ProgramData%\Google\Chrome Remote Desktop

• Paste that into File Explorer or Run (WinKy+R)
• Delete the entire folder
• This step clears the hidden configuration that survives uninstalling

3. (Optional) Clear leftover registry keys

• Open regedit
• Navigate to:

  HKEY_LOCAL_MACHINE\SOFTWARE\Google\Chrome Remote Desktop
  

• If it exists, delete it

🔁 Reinstall

1. Go to: https://remotedesktop.google.com/
2. Reinstall the host app
3. Set up the device again — it should now work

🧠 Notes

• %ProgramData% is a system-level path and is often overlooked during standard uninstalls
• This folder stores machine-specific configuration and causes account switching to fail
