After upgrading to Windows 8/8.1 or windows 10, Solid MultiConnect™ may give an error when starting up. The reason for this is that it needs to start Windows Mobile Device Center which requires .NET Framework 3.5 which often is not enabled by default.

The simplest way to enable the .NET Framework 3.5 on a small number of Windows 8/8.1/10 client machine is through Turn Windows features on or off:

1. On the Start Screen begin typing "turn windows features on or off", select Settings in the search pane, and click on Turn Windows features on or off.

   Windows 8:

   Windows 10:

2. Check the box next to .NET Framework 3.5 (includes .NET 2.0 and 3.0)

   

3. Click OK

   The wizard will search for required files and then prompt you to download files from Windows Update.

4. Select Download files from Windows Update.

   

5. After the wizard completes, click Finish.

6. When finished, plug the USB connector of the Windows Mobile device into the computer. Windows will download the drivers and install Windows Mobile Device Center (WMDC).
