AMPL Installation Wizard

Here are instructions to upgrade AMPL-Gurobi on Microsoft Windows:

  1. Unzip the supplied AMPL-Gurobi file, which will be named something like amplgurobi11.0.0_mswin64.zip. This will create a folder called AMPL, which contains the AMPL-Gurobi software. (Note that your unzip utility may embed this AMPL folder inside a folder such as amplgurobi11.0.0_mswin64).
  2. Copy your existing ampl.lic license key to the AMPL folder that was created in the previous step.
  3. Replace your old AMPL folder with the new one.
  4. If you are using a floating license server for AMPL-Gurobi, please follow the additional instructions for ampl_lic.
