My CCW V20 is working with the help of TechSupport.
The problem was the language adjustment of Windows, this must be Englisch!
In my case it set to Dutch, but I can imagine that a of people living in other countries than the US and UK / Ireland use different language settings in there OS.
If it is a problem to use the Englisch language setting in the OS of the host, you can think about a virtual machine.
Good luck!
