Unreal Engine 4 (UE4) is a powerful game engine that requires a robust set of prerequisites to function optimally. The -x64- setup refers to the 64-bit architecture requirements for UE4. In this guide, we'll walk you through the essential prerequisites and setup steps to ensure a smooth and efficient UE4 experience.
Do not separate the prerequisites from your game installer. Run them as a custom action at the end of your own installer (e.g., using Inno Setup or InstallShield) with the /quiet flag.
