The following table lists the software that is installed by the prerequisite installer. The source for the installer is under Engine/Source/Programs/PrereqInstaller.
If you use Perforce to get the Unreal Engine source code, you'll also find precompiled binaries in the same Engine/Extras/Redist/en-us folder of the Perforce repository. You can find the installer, with separate executables for 32-bit and 64-bit Windows, in the Engine/Extras/Redist/en-us folder under your Unreal Engine installation location. However, after the engine is completed it will be possible to use it for your own project. However, you may need to run the prerequisite installer yourself if you build Unreal Engine from source, or if you need to prepare a computer with all the Unreal Engine prerequisites for a specific purpose-for example, if you are setting up a fresh computer to act as a Swarm Agent. The engine is still very much in development and will require a lot of work before it is completed. When you install Unreal Engine through the Epic Games Launcher, the Launcher automatically installs these prerequisites for you. The Unreal Engine includes a prerequisite installer that installs everything needed to run the editor and engine, including several DirectX components and Visual C++ redistributables.
