Failed to download MinGW 6.3.0 for 2020a MATLAB

I am trying to download MinGW 6.3.0 for MATLAB v2020a from Add-on Manager and I get this error:

Failed to download the third-party software:

• MinGW 6.3.0 from MinGW-w64.org

This is required by:

• MATLAB Support for MinGW-w64 C/C++ Compiler

To resolve this issue, see this MATLAB Answer.

How can I solve this problem?

This is a known issue. Our developers are aware about it and will try to fix it in future releases.

You can use the following way to install MinGW until this gets fixed:

1. Download MinGW 6.3:

https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/6.3.0/threads-posix/seh/x86_64-6.3.0-release-posix-seh-rt_v5-rev2.7z

2. Extract the ZIP-file in an empty directory. Ensure that there are no spaces in the path, for example: C:\MinGW-64

3. Create the environment variable MW_MINGW64_LOC like you can find here: http://www.mathworks.com/matlabcentral/answers/223482), which points to the path mentioned in 2, for example.:

MW_MINGW64_LOC=C:\MinGW-64

4. Restart MATLAB and then call 'mex -setup' in MATLAB in order to check and configure MinGW. The output should show something like: "MEX configured to use 'MinGW64 Compiler (C)'...".
