NWBC 5.0 does not start on Windows 10

Hi All,

When I try to open the NWBC on windows 10 , I get error message "Microsoft .NET Framework 4.5 is not installed.". After then I try to install .NET Framework 4.5 but I get error message again " 1. Microsoft .NET Framework 4.5 is already a part of this operating system.  You do not need to install the .NET Framework 4.5 redistributable. 2. Same or higher version of .NET Framework 4.5 has already been installed on this computer.".

I can not solve this problem yet.

Thanks ,
