Apollo Pro is a standalone application with a very small footprint. To install, download the zip file. Please note that you will need an Oracle client installed in order to use Apollo Pro.
After downloading, unzip to a directory of your choice. Once unzipped, and after running Apollo Pro for the first time, you can add the templates located under %install_dir%\Templates to the template browser. View the help file for instructions on how to do this.
