.NET 4.6 required, please that it is installed

[MircoBabin]

If .NET 4.6 is missing the gui just reports ERROR without logfile. Starting the commandline tool shows the error "Method not found !!0[] System.Array.Empty()".

It would be very great if the installation of .NET 4.6 is checked. And a decent errormessage is given in case it doesn't.

This will be very helpfull to new users. Now the tool appears to be broken, because .NET 4.6 is missing.
