Information and installation instructions

### Installation

To install this license on a computer where Gurobi Optimizer is installed, copy and paste the following command to the Start/Run menu (Windows only) or a command/terminal prompt (any system):

grbgetkey
The grbgetkey command requires an active internet connection. If your computer has no internet access, or you get no response or an error message such as „Unable to contact key server“, Please click here for additional instructions.

To install a license key automatically, the grbgetkey program needs to be able to communicate with the Gurobi website (http://www.gurobi.com). It may fail if the computer:

• has no Internet connection
• has restricted access due to a firewall
• uses a proxy server

Alternately, here are manual instructions to obtain or update a license key file for your computer.

1. Run the grbprobe command on the computer where the license will be installed.
2. Complete the following form using the output from the grbprobe command:
No ID is set
