Here are instructions to add or upgrade Gurobi Solver to an existing AMPL installation on Microsoft Windows:
amplgurobilink9.0.1_mswin64.zip
. This will create a separate folder called AMPL, which contains the Gurobi Solver software. (Note that your unzip utility may embed this AMPL folder inside a folder such as amplgurobilink9.0.1_mswin64
).
