Clio Drive Does Not Show Up and Shows Errors: “Something went wrong with Drive. Please restart the Clio desktop app." and/or “Letter could not be changed. Please try again.”


  • Clio drive does not Mount
  • A: Drive doesn't show up for Clio Drive
  • Error: “Something went wrong with Drive. Please restart the Clio desktop app"
  • Error: "Letter could not be changed. Please try again.”


  • Clio Desktop
  • Clio Drive
  • Windows Server

Additional Information:

  • Windows Server installations do not include the Webclient service by default which is needed for Clio Drive to operate. This must be installed before Clio Drive will work.
  • See Microsoft's Support article regarding this here.


Note: Please note that the following troubleshooting steps only pertain to systems running Windows Server. If you are running into the same issue using other versions of Windows after verifying Webclient is running as outlined below, please contact us.


To check your Windows version:

  1. Click the Start button
  2. Click Settings
  3. Click System
  4. Click About


  1. Press Windows Key + R
  2. Type winver
  3. Press Enter


To Install WebDAV Redirector (which includes Webclient)

Certain Windows Server versions do not include support for WebDAV out of the box. Please follow the ‘Installing the WebDAV Redirector’ instructions in Microsoft’s IIS documentation, and reboot before launching Clio Desktop again.


To check if Webclient is running:

  1. Press Windows Key + R
  2. Type services.msc
  3. Press Enter
  4. Search the Services list for WebClient

WebClient is a Microsoft application that is required by Drive for mounting. Verify that it is installed and running. Right-click on the Start menu > Run and enter ‘services.msc’. The list of services that appears should include Webclient, and its Startup Type should be either Automatic or Manual. Edit the service and set its startup type to Manual if this is not the case. Reboot after updating the startup type of the service.



Furthermore, in order to verify if Webclient is up and running, you can open Command Prompt and run the following command:

reg query HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\NetworkProvider\HwOrder


This value of this key should contain webclient:



If the key does not contain webclient, the following troubleshooting steps are best handled by your IT personnel if you are not comfortable with editing your Registry. Clio Support Agents will not be able to assist with this step:

If webclient is not included, open the Registry Editor and navigate to ‘HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\NetworkProvider’ using the folders on the left-hand side. Double-click on the HwOrder key and add webclient to the beginning of the key. Reboot after updating the registry.
