Problems with installing gurobi academic licence

1

Hello,
I use cvx with gurobi solver. I renewed my accademic licence, but I can not install new gurobi.lic file.
The included printouts after cvx_grbgetkey(), and cvx_setup commands.
I hope that all necessary data are below.

cvx_grbgetkey(‘4986fda6-5f12-11eb-9…’)

The attempt to retrieve the license key failed with the following error:

Have you tried calling gurobi functions from MATLAB without using CVX? You need that to be working correctly for there to be any hope of getting gurobi to work under CVX.

Thank you for the advice. Gurobi works with cvx.
Many thanks.
