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. Photoshop Elements is designed for amateur rather than pro photographers, but it does offer a number of photo editing features that might be sufficient for your needs. 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, 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. 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.
