Before using the Gurobi Optimizer, you'll need to install the software on your computer. If you haven't already done so, please go to our download page. Find your platform (32-bit or 64-bit Windows) and choose the corresponding file to download.
Your next step is to double-click on the Gurobi installer that you downloaded from our website (e.g., Gurobi-8.1.1-win64.msi for the 64-bit version of Gurobi 8.1.1).
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 8.1.1 files in
directory c:\gurobi811\win64 (or c:\gurobi811\win32 for 32-bit
Windows installs). The installer gives you the option to change the
installation target. We'll refer to the installation directory as
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
msiexec /i Gurobi-8.1.1-win64.msi /norestart
If you are unfamiliar with running command-line commands on a Windows system, you can learn more here.
Installing 32-bit and 64-bit simultaneously
You should normally only install the Gurobi version that is targeted to your platform (32-bit or 64-bit Windows). If you want to install both on the same machine, note that the Gurobi installer sets Windows environment variables that will point to one particular version. This can cause confusion, particularly when a program asks Windows to load the Gurobi DLL. If you understand the implications, feel free to install both.
You are now ready to proceed to the section on Retrieving Your Gurobi License.
