    Could you try setting the system environment variable GRB_LICENSE_FILE to point to the gurobi license file? Please check also the article How do I resolve an "Error 10009: Unable to open Gurobi license file"? – Gurobi Help Center

    Thanks for your answer. I have set the system environment variable to point to the gurobi licence file, but the error message still occurs. I also tried to implement the steps described in the article, but that didn't help either.

    Hi Ananthi, what OS are you using?

    Are all of you running Linux on your Windows machine through Windows Subsystem for Linux (WSL)?  In addition, please answer the following questions:

    • What version of WSL are you running?
    • Did you install your Gurobi license on the Host Windows machine or the WSL Linux environment?
    • What type of Gurobi license are you using?

     

    If using WSL2 please view the knowledge base article on setting up a license to work in this environment.
