Visual Cobol 4.0 for Visual Studio 2017

 Hi, I installed new virtual PC for Visual Cobol testing - Windows 10 Professional, Visual Studio 2017 Professional, Visual Cobol 4.0 trial 30 day. I am not able to load any solutions from Sample Micro Focus directory (e.g. WinHello.sln). Visual Studio loading solution, but does not finish the operation and freezes. I have to use Task Manager for kill it. I am not even able to create a new project based on a cobol. (creating solutions ..... and nothing happens). What is wrong? Can you help me? Regards Petr
