License error for JuMP

Hi All,

I have installed JuMP (“0.18.5”) and Gurobi (“0.6.0”). I have put a valid license for Gurobi in its corresponding folder. However, I get the following error when I want to solve my optimization problem. Can you please let me know why I am getting this error.

ERROR: LoadError: Invalid Gurobi license

Thanks in advance!

Here is the Gurobi support:

You either didn’t set GRB_LICENSE_FILE when installing the license in a non-default location, or your license version doesn’t match the version of Gurobi that you are running.
