Libraries required to run C++ applications.
A fresh installation of Windows 10 or 11, while robust, does not include the specific versions of the Visual C++ Redistributables that Unreal Engine 4 requires. Similarly, while modern Windows includes DirectX 12, older DirectX 9 and 11 components (which many UE4 projects still rely on for broad hardware compatibility) may be absent or incomplete. The ue4prereqsetup-x64.exe automates the remediation of this gap. It queries the Windows Registry to determine if the required versions are installed, downloads them from either a local cache (often bundled with the engine) or Microsoft’s official servers, and executes their installers in silent mode. This process shields the user from technical complexity; they need only run one file, not hunt down three different Visual C++ redistributable packages and manually run DirectX Web Installer.
When game developers build projects using Epic Games' Unreal Engine 4, the final application requires specific engine dependencies to run properly on a user's Windows operating system. Instead of forcing players to download multiple individual software packages, Epic Games bundles these dependencies into a single installer: the UE4 Prerequisites Setup.
