Note: This process is not available for "self-service" Individual Named-User Academic licenses, which are listed as "Free Academic Trial" in the Gurobi User Portal.
For situations in which the computer is on a secure network without internet access or the network has a firewall that prevents the computer from connecting to the license key server, Gurobi has a manual process to generate the license file:
-
Once Gurobi is installed on the target machine, run grbprobe
on
the target machine to generate a report regarding your system.
info : grbprobe 13.0.2, build v13.0.2rc1
info : Platform is mac64 (darwin) - Darwin 23.3.0 23D60
HOSTNAME=mycomputer
HOSTID=4abc42da
PLATFORM=mac64
USERNAME=myuser

CONTAINERID=host:NUDRCOL
TAG=8675309867530986753098 -
Next, using any computer connected to the internet, go to the Licenses
table
on your
Gurobi User Portal.
Click the installation icon
on the correct license from the table of licenses. In the popup window, select "GENERATE MANUALLY".

This will display additional instructions and a form where you can enter
the information returned by grbprobe:
