AMPL Installation Wizard

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

Unzip the supplied AMPL-Gurobi file, which will be named something like amplgurobi6.0.0_mswin32.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 amplgurobi6.0.0_mswin32).
Copy your existing ampl.lic license key to the AMPL folder that was created in the previous step.
Replace your old AMPL folder with the new one.
If you are using a floating license server for AMPL-Gurobi, please follow the additional instructions for ampl_lic.
