Why does't MATLAB R2016b recognize a C Compiler?

I know this Question has already been asked several times but I still don't manage to solve it. I run Matlab R2016b on Windows 10.

Everytime I compile a SimuLink Program I get the following error message :

"An installed compiler was not detected. Certain simulation modes, as well as host-based coder builds require that a compiler be installed. Please install one of the supported compilers for this release as listed at:

http://www.mathworks.com/support/compilers/R2016b/win64.html

MATLAB must be restarted after the compiler is installed.

Once you have a supported compiler installed, either select it to be the MEX compiler or override the MEX compiler with: slrtsetCC -setup"

Here is what I did:

- I installed Microsoft Visual Studio Professional 2015 and have now

- Microsoft Visual C++ 2015 and also

- Microsoft .NET Framework 4.6.1 SDK on my System (both are listed in the above link).

- When I run slrtsetCC -setup in the MATLAB Command Window, I get the following:

        Select your compiler for Simulink Real-Time.

        [1] Microsoft Visual C++ Compilers Professional 2015 in C:\Program Files >>(x86)\Microsoft Visual Studio 14.0

        [0] None

        Compiler:1

        Verify your selection:

        Compiler: Microsoft Visual C++ Compilers Professional 2015
        Location: C:\Program Files (x86)\Microsoft Visual Studio 14.0

        Are these correct [y]/n?y

        Done...

Where I selected Compiler: 1 and verified ( y ).

- When I now try compiling my Program, I still get the same error message that there is no Compiler detected (restarting MATLAB doesn't change that).

- What could also be helpful to answer my question:

When I type myCCompiler = mex.getCompilerConfigurations('C','Selected'), I get

    myCCompiler =

    0×1 CompilerConfiguration array with properties:
    Name
    Manufacturer
    Language
    Version
    Location
    ShortName
    Priority
    Details
    LinkerName
    LinkerVersion
    MexOpt

Here I should be able to see the properties of the selected C Compiler, but it doesn't show anything.

When I type mex -setup, I get

    Error using mex

    No supported compiler or SDK was found. You can install the freely available MinGW-w64 C/C++ compiler; see Install
    MinGW-w64 Compiler. For more options, visit http://www.mathworks.com/support/compilers/R2016b/win64.html.

Which is the same link as before..

There could be a possibility that while installing Visual Studio, "Typical" setup option was chosen, which does not install the Visual C/C++ compiler by default. This is seen in Microsoft's documentation:

https://msdn.microsoft.com/en-us/library/hh409293.aspx

To resolve this issue, re-run the Visual Studio 2015 installer again and choose to perform a "Custom" setup. Then during installation, make sure to enable "Visual C++" under "Programming Languages".

Also, the function 'slrtsetCC' is for the Simulink Real-Time product which is independent of Simulink/Enbedded Coder products.

Moreover, the verbose mode for "mex -setup" will be helpful in order to see what is going on under the hood. This can be done by including the -v flag, shown as follows:

>> mex -v -setup

Thank you very much for your answer, this was indeed the problem. The thing is that I recently realized that i need VS2013 because the 2015 Version unfortunately doesn't work for Simulink Real Time Applications. So I installed the 2013 Version and then I had the same problem again. Again, I restarted the 2013 Installer, but even though I enabled every option it still doesn't work. (same error message)

Doesn't VS2013 provide VisualC++ ? Should I install both version of Visual Studio?
