How do I install Gurobi Optimizer?

Your next step is to double-click on the Gurobi installer that you downloaded from our website (e.g., Gurobi-12.0.0-win64.msi for the 64-bit version of Gurobi 12.0.0).

Note: if you selected Run when downloading you've already run the installer and don't need to do it again.

By default, the installer will place the Gurobi 12.0.0 files in the directory c:\gurobi1200\win64. The installer gives you the option to change the installation target. We'll refer to the installation directory as <installdir>.

Note that the installer can also be used to repair or remove a past installation.

Command-Line Installation

You can also install Gurobi using the command-line interface to the Windows Installer. Open a cmd prompt, use cd to go to the directory that contains the Gurobi installer image, and enter the following command:

msiexec /i Gurobi-12.0.0-win64.msi /norestart

Helpful tools

To work with compressed files within Gurobi Optimizer, we recommend that you install gzip (www.gzip.org) and/or 7zip (www.7-zip.org).

Your next step is to double-click on the appropriate Gurobi installer (e.g., gurobi12.0.0_macos_universal2.pkg for Gurobi 12.0.0) and follow the prompts.

By default, the installer will place the Gurobi 12.0.0 files in /Library/gurobi1200/macos_universal2 (note that this is the system /Library directory, not your personal ~/Library directory).

Your <installdir>  will be /Library/gurobi1200/macos_universal2.

Your next step is to choose a destination directory. We recommend /opt for a shared installation (assuming you have sudo privileges to write in that directory), or your home directory for a private installation, but other directories will work as well. You'll need to change your working directory to the destination directory (e.g., cd /opt or cd /home/jones), copy the Gurobi distribution to that directory, and then extract the contents:

tar xvfz gurobi12.0.0_linux64.tar.gz

or

tar xvfz gurobi12.0.0_armlinux64.tar.gz

This command will create a sub-directory /opt/gurobi1200/linux64 or /opt/gurobi1200/armlinux64 that contains the complete Gurobi distribution (assuming you chose /opt). Your <installdir> will be this subdirectory.

Gurobi Optimizer makes use of several executable files. To allow these files to be found when needed, you will need to modify a few environment variables:

• GUROBI_HOME should point to your <installdir>.
• PATH should be extended to include <installdir>/bin.
• LD_LIBRARY_PATH should be extended to include <installdir>/lib.

For guidance on setting these environments please refer to How do I set system environment variables for Gurobi?
