This is the full installation of the Pegasus RO server.
All you have to do is right click, or double click to unzip the file in your desired destination on your hard drive (normally in the Programs Files folder).
After make a shortcut for your setup, and PegasusRO Patcher.exe files to your desktop
Run the setup file to get dimensions correct for your screen resolution.
Run the patcher (do this every time to start the game so you will never have issues with new items)
Play the game 🙂
