Unhandled exception thrown when run connectMATLAB()

hi, I am currently building my c++ program running with Simulink. I have tried the code I found from the website: https://uk.mathworks.com/help/matlab/matlab_external/run-simulink-simulation-from-c.html

However, it seems I've some problem when I run this code :

std::unique_ptr<MATLABEngine> matlabPrt = connectMATLAB(session);

When I run connectMATLAB() it gives me unhandled exceptions:

Exception thrown at 0x00007FFE495EA388 in ConsoleApplication1.exe: Microsoft C++ exception: std::runtime_error at memory location 0x00000098BA8FD678.

It navigates me to the row 579 in the excptptr.cpp file.

I have no idea, what happen.

Same problem here with Visual Studio 2015 Pro. With the former C interface using engOpen(), connection is done. With the C++ interface the exception occurs when cpp_engine_create_session(); is called from within ENGINE_FACTORY_IMPL.HPP.
