To setup a license file for a free individual academic license on your computer for research, teaching, or coursework purposes, connect your computer to the university network, then follow these instructions for obtaining a named-user academic license.
Detailed setup help can also be found in the Gurobi Quick Start Guides.
Please note: Your computer must be connected to the university network for the grbgetkey command to work. You can connect your computer either directly or via a VPN that tunnels all traffic through the university network. Once the license file is setup, your computer does not need to be connected to the university network. You can repeat this process to obtain licenses for additional computers or new Gurobi versions.
