Hello,
I have downloaded Gurobi 9.5.0 along with its license (academic). I am unsure if this is a gurobi side issue or if its MATLAB, but whenever I try to use Gurobi with YALMIP, or even just run the setup for the paths, I get the following error:
Error using gurobi_setup (line 89)
Invalid MEX-file 'C:\gurobi950\win64\matlab\gurobi.mexw64': The specified module could not be found.
What is odd is that the mex file is called exactly the same name as specified in the error, and has the exact same path.

The mex file is expecting a specific module, but can't find it. This will sometimes happen if you try to run a mex file from a new release on an old release, but since you are using R2020a, that seems an unlikely cause.
I would expect that you need to install some software that the compiler assumed would be on the target machine. I don't know how you would find out what that would be.

Use the Dependency Walker to find out, which library is missing:
This might be the runtime libraries of the compiler.
