Software Installed by the Prerequisite Installer

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. When you install Unreal Engine through the Epic Games Launcher, the Launcher automatically installs these prerequisites for you. 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 .

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.

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. The source for the installer is under Engine/Source/Programs/PrereqInstaller .

The following table lists the software that is installed by the prerequisite installer.

DirectX Components

Visual C++ Redists

XInput 1.3 (April 2007)

Visual C++ 2010 CRT

X3DAudio 1.7 (February 2010)

Visual C++ 2010 OpenMP library

XAudio 2.7 (June 2010)

Visual C++ 2012 CRT

D3D Compiler 4.3 (June 2010)

Visual C++ 2013 CRT

D3DCSX 4.3 (June 2010)

Visual C++ 2015 CRT

D3DX9 4.3 (June 2010)

Visual Studio 2019 redistributable

D3DX10 4.3 (June 2010)

D3DX11 4.3 (June 2010)

The most important DirectX components from that list are the XInput, X3DAudio, and XAudio dependencies. These aren't included in standard installations of DirectX (and aren't distributed with Windows by default), so they have to be installed manually or distributed with the application.

Graphics Card Drivers

We currently recommend using the latest stable releases from each card manufacturer:

Performance Notes

This list represents a typical system used at Epic, providing a reasonable guideline for developing games with Unreal Engine 4:

  • Windows 10 64-bit

  • 64 GB RAM

  • 256 GB SSD (OS Drive)

  • 2 TB SSD (Data Drive)

  • NVIDIA GeForce GTX 970

  • Xoreax Incredibuild (Dev Tools Package)

  • Six-Core Xeon E5-2643 @ 3.4GHz

If you don't have access to Xoreax Incredibuild (Dev Tools Package), we recommend compiling with a machine having 12 to 16 cores; however, we encourage you to read the Hardware Benchmarks (2017) reference to learn more about compiling with and without XGE.
