Hi Enrique,

could you test whether Gurobi and your license have been installed properly by executing \(\texttt{gurobi.sh}\) in a terminal window as described here.

Best regards,
Jaromił

I have a similar issues and I have checked gurobi.sh in my terminal, I do have a valid license but Open Solver does not solve whenever I pick gurobi as the solve engine

A similar problem seems to be solved in the Community Post How to use Gurobi in tandem with OpenSolver inside of Excel. Does this help?
