Installing Unreal Engine
To use Unreal Engine, you must first install the Epic Games Launcher:
- Access the website at https://www.unrealengine.com.
- Register and download the Epic Games Launcher.
- Install and start the launcher.
- Click the Unreal Engine tab on the left-hand side.
- Click on the Library tab that appears at the top of the screen.
- Click the + button next to ENGINE VERSIONS to add a version of Unreal Engine to the launcher. You can use the newest version available.
- Click the Install button. The launcher will start downloading the files needed for installation and may take a long time to complete.
- Click the Launch button to start an already installed version. It is possible to have multiple versions of Unreal Engine installed on the same machine – you simply set one of them as the current version. The Launch button at the top right of the launcher will start the current version.

The Blueprint Visual Scripting system is already a well established and stable technology. This book uses version 5.0.0, but the examples created in this book should work without problems in later versions.
