Can I use Microsoft Visual Studio 2017 compilers with MATLAB R2021a?

I want to use mexopencv, but I can't set Microsoft Visual Studio 2017 in MATLAB, evenso I installed VS2017.

This is error when I am running mexopencv and mex -setup:

Error using mexOpenCV (line 73)
The OpenCV libraries were built using 'Microsoft Visual C++ 2017'.
 Your compiler is 'MinGW64 Compiler (C)'.
 These compilers may not be compatible.
 Note that you can select a compiler using 'mex -setup' command.

Hi Adnan,

By looking at the output from "mex -v -setup", the issue is caused by the Windows registry entry not pointing to the correct installation folder.

To resolve this issue for Visual Studio 2017, please reinstall it in "C:\Program Files (x86)\Microsoft Visual Studio\2017" and run "mex -v -setup" in MATLAB.

Since MATLAB has stopped relying on the registry entry from Visual Studio 2019, such issues will not be there with VS 2019 and later versions of VS.
