Cannot make c++ class from a specific project

I just installed Visual Studio 2015. There is an option to make a new C++ class from other projects, (even older ones), but not from the specific one. I tried to import settings from other projects, but I am not sure, which .ini file to import (guess something from the Settings/Platforms/Windows?). It says ‘No compiler was found. In order to use C++ code, you must first install Visual Studio 2015’. Hope you guys could help me, because I do not want to import everything to a new project, even if it might help.
