# AMPL Installation Wizard

Here are instructions to add 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 `amplgurobilink9.5.2_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 `amplgurobilink9.5.2_mswin64`).
3. Open this new AMPL folder and copy all its files to the folder where AMPL is already installed on your computer.
4. Open a Windows command prompt and type the commands:

       cd C:\AMPL
       fingerprint -o fp.out

   The `cd` command should be modified to reflect the folder where AMPL is installed on your computer. 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.
5. When you receive your license key, simply copy the license key file to the folder where AMPL is installed.
6. If you are configuring a floating license server for AMPL-Gurobi, please follow the additional instructions for ampl_lic.
