Hi @Nagendra Babu Ellapu,

If you're having trouble downloading MinGW-w64 through the MATLAB add-on manager, you can try downloading MinGW directly instead. Just make sure to download the correct version of MinGW for your version of MATLAB. You can refer to this MATLAB Answers post for guidance on the appropriate MinGW-w64 version for your MATLAB release:

Kindly refer the following steps to download minGW directly instead of add-ons:

1. Download MinGW-w64 version 6.3 for R2018b and later:

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/download

2.Extract the downloaded zip folder into an empty directory, and then create an environment variable with the MinGW path. For setting the 'MW_MINGW64_LOC' environment variable, refer to Step 2 in the above MATLAB Answers post.

3. Now restart MATLAB and call 'mex -setup' to configure minGW.

Refer to following MATLAB Answer posts for more details:
