The error may be caused by a network connection error. In some cases, a firewall or antivirus is blocking the connection.Try to deactivate any such software temporarily for the download.

Workaround is to install MinGW Compiler manually:

1. Delete the MinGW installation files from: C:\Users\<username>\MATLAB\Downloads\SupportPackages\R2016b\downloads\R2016b If you do not find the MinGW files continue from step 2.

2. Download the installation files from the following webpage:

https://sourceforge.net/projects/tdm-gcc/files/TDM-GCC%2520Installer/Previous/1.1309.0/

You will need the file tdm64-gcc-4.9.2.exe for 64-bit.

3. Start the installation. Deactivate the option 'Check for updates' on the welcome screen. Choose a path without spaces, e.g.: C:\TDM-GCC-64

4. After the installation create the environment variable: MW_MINGW64_LOC=C:\TDM-GCC-64 This is described on the following page: http://www.mathworks.com/help/matlab/matlab_external/compiling-c-mex-files-with-mingw.html

5.Restart MATLAB and type below command in MATLAB command prompt:

>>  mex -setup

This should now recognize the MinGW.
