First, you’ll need the latest version of Galaxy installed on your machine. You can find instructions on how to do this here.
After you have installed Galaxy, please run it, and log in using your GOG.com account credentials - the same that you use on our website. Lastly, go to the Library tab in GOG Galaxy. You can switch tabs using the bar at the top of Galaxy window. Click on the game you wish to install, and you'll be taken to that game page. Here you have few options, but click on INSTALL to proceed. You will be presented with a new window, where you can change:
- game language (only for supported games),
- installation directory,
- whether or not you want to create a shortcut,
- auto-update options,
as well as read End User Agreement. To start the installation process click on CONTINUE. The game will be added to the side-bar on the left-side of Galaxy window. Installation progress bar will be displayed beneath the game title. Once it’s finished, you can click on PLAY to start the game.
