"Your client does not support opening this list with Windows Explorer" error in SharePoint
Posted by Jay Allred on 21 January 2014 03:20 PM

You get the following error when trying to open a document library using "Open with Explorer", "Your client does not support opening this list with Windows Explorer". One possible fix for this is below:

  1. Click start and type regedit and hit enter. This should start Registry Editor
  2. Find the following key:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters
  3. If not already present, create a DWORD Value named BasicAuthLevel and set its value to 2.
  4. Reboot or restart the WebClient service in Services.
