To install a new free academic license (for research, teaching, or coursework), connect your computer to the university network, then follow these instructions for obtaining a named-user academic license.
Detailed installation help can also be found here: 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 key is installed, your computer does not need to be connected to the university network. You can repeat this process to install licenses for additional computers or new Gurobi versions.
