fialed to install MinGW compiler

Hi:

I failed to install the C/C++ compiler in Matlab. below are my steps:

in Matlab window, use Add-Ons, search the MinGW, I followed all the steps in the web and it showed installed successfully.

however, when I type the 'mex -setup' in Matlab window, it showed:

    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/current_release/.

I tried to set the environment variable, but I even could not find where it was installed.

I also tried to download the file and installed by myself, but it failed too.

could anyone help me solve this problem?

Thanks!

The -v is important for this purpose.
