Some computers cannot run the grbgetkey command. For example, the computer may be on a secure network without internet access, or the network may have a firewall that prevents the computer from connecting to the license key server.
Gurobi has a manual process for these situations:
- Login to the Gurobi website and select the license ID from https://www.gurobi.com/downloads/licenses/.
- Following the information section, is the "Installation" section. Click on the link marked "Please click here for additional instructions".
- Complete the form with your computer's information.
- Download the gurobi.lic license key file and install it. (See How do I put the license key file in an alternative location? for information about the default directory for this file).
Note that this process is only available for commercial customers; it is not available for free academic licenses or for free licenses for online courses.
