# AMPL Installation Wizard

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

1. Unzip the supplied AMPL-Gurobi file, which will be named something like `amplgurobi11.0.3_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 `amplgurobi11.0.3_mswin64`).
2. Move this AMPL folder to your preferred location. Virtually any folder will work such as `C:\AMPL` or `C:\Program Files\AMPL`.
3. You will need a license key for AMPL - even if you already have a license key for the standalone Gurobi Optimizer. To get system information needed for a license key, use the supplied Scrolling Window program `sw.exe`, which is described in detail in the User Guide. Open the folder where AMPL is installed, run `sw.exe`, then type the command:

       fingerprint -o fp.out

   This will generate a fingerprint file named `fp.out` in the AMPL folder. To request your license key (after we have received your payment or a Gurobi sales representative has approved your request to evaluate AMPL), email the `fp.out` file to license@gurobi.com.
4. When you receive your license key, simply copy the license key file to the folder where AMPL is installed.
5. If you are configuring a floating license server for AMPL-Gurobi, please follow the additional instructions for ampl_lic.
