An error
ERROR 10009: Version number is xx, license is for version yy
indicates that you are trying to use a License for version yy for Gurobi version xx.
For example, "ERROR 10009: Version number is 12, license is for version 11" indicates that you are trying to use a license for Gurobi v11 for Gurobi v12.
Note that Gurobi licenses are backwards compatible so a v12 license will work for v11.
Update your Gurobi license to the latest version.
- For WLS and Gurobi Instant Cloud licenses, there is no need to make any update.
- For self-serve Academic Named-User licenses, please request a new license via the User Portal to be able to use the newer version of Gurobi.
For all other licenses, please log into your Gurobi account and re-run the grbgetkey commang for your license. See How do I retrieve and set up a Gurobi license? for detailed instructions for each license type.
