I'm using R2016b on Windows and have a number of compilers installed. Previously I had MINGW installed via the add-on and that worked; however, I need to use MSVC. Typing `mex -setup` immediately produces the following error with no option to search for installed compilers or make a selection.

>> mex -setup 
Error using mex
No supported compiler or SDK was found. You can install the freely available MinGW-w64 C/C++ compiler;

Hi,

from the error it seems that you don't have any C++ compilers installed on your machine. Here's a link for the supported compilers in R2016b. Since you want to use Visual C++ as you compiler please take note of following points:

Only Professional edition is supported for Microsoft Visual Studio 2012/2013/2015.
If you have professional then make sure that you have installed the C++ compiler. It may not be part of the standard installation of Visual Studio hence you will need to do a custom installation.
Finally if you don't have Professional edition then you need to install Microsoft Visual studio 2017 and add a patch to MATLAB. The instructions for the patch can be found here. With this patch added R2016b supports all the editions of Visual Studio 2017.
