Hello,
I want to ask some help for installing a C-language complier 'Mingw-w64', it has installed on a Matlab 2019b and work pretty well.
However, i moved to 2021a recently since a konw bug on matlab (the 'invoke' code for instrument control). the compiler was firstly installed automaticly for first time matlab launch. Then when I compile my previous code, it asked to instal the compiler that is shown installed in adds-on.
when I type 'mex -setup -v' in command window, it shows a 'Yes' for environement variable and a 'No' for the 'gcc.exe'. Thus i unstalled the compiler in addson and i wanted to reinstal the complier. However, this time download of the software is blocked.
Any one suffered a similar issue?

Yes, all the installations were via the Add-Ons explorer for both 2019a and 2021a. The 2021a asked to update the packages at the first launch, and I saw all the add-ons of 2019a on the list. Besides other packages, only the 'Mingw-w64' can not be installed. I tried three different times, and it never worked.

Go to the Add-Ons explorer and type mingw64. Then, proceed with downloading and installing the compiler.

Hi, i had tried the solution mentioned in the forum and i got the install log file. Which shows that the problem is due to internet connection.
I want to ask to sent me the package to install the minGW-W64, since I can not desactivate the anti-virus program.
Regards,
Kejun
