Gurobi provides MD5 hashes to check whether the file you downloaded is not corrupt and contains exactly the intended data.
Depending on your operating system, there are different ways of verifying the integrity of the files. You can always find a data file with the correct MD5 next to the file link on our downloads page.
Windows
Download the installation file and the corresponding checksum file to the same directory and then run the following command in a PowerShell terminal:
certutil -hashfile Gurobi-11.0.3-win64.msi MD5
To show the contents of the downloaded MD5 file and compare it with the output from above, you can run:
cat .\Gurobi-11.0.3-win64.msi.md5
Alternatively, you can inspect the file in a text editor.
macOS
Download the installation file and the corresponding checksum file to the same directory and then run
md5sum -c gurobi11.0.3_macos_universal2.pkg.md5
If the file has been downloaded correctly, you will see this output:
gurobi11.0.3_macos_universal2.pkg: OK
Linux
Download the installation file and the corresponding checksum file to the same directory and then run
md5sum -c gurobi11.0.3_linux64.tar.gz.md5
If the file has been downloaded correctly, you will see this output:
gurobi11.0.3_linux64.tar.gz: OK
