# AMPL Installation Wizard

Here are instructions to add or upgrade Gurobi Solver to an existing AMPL installation on Microsoft Windows:

1. Determine the folder where AMPL is installed on your computer.
2. Unzip the supplied AMPL-Gurobi file, which will be named something like `amplgurobilink11.0.0_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 `amplgurobilink11.0.0_mswin64`).
3. Open this new AMPL folder and copy all its files to the folder where AMPL is already installed on your computer.
