Step-by-Step: How to Create an Offline Installer for UE4

Offline / local installation options (practical approaches)

  1. Use the Epic Games Launcher to download the engine on a machine with internet, then copy the engine directory:

    • Install UE4 via Epic Games Launcher on an internet-connected PC.
    • Locate the engine install folder (commonly C:\Program Files\Epic Games\UE_4.xx on Windows).
    • Copy the entire UE_4.xx folder to external storage (USB drive, external SSD).
    • On the offline target machine, place the folder in the desired location and register it with the Epic Games Launcher (if accessible) or use the engine binaries directly for command-line builds. Note: Launcher registration typically still requires internet for account sign-in.

  2. Use the GitHub source build:

    • Epic provides UE4 source on GitHub to users who link their Epic account. Clone the repository on a machine with internet, run Setup.bat and GenerateProjectFiles, then build the engine. Copy the built binaries to the offline machine.
    • This method is suited if you need source modifications or a fully self-contained build. It requires a GitHub account linked to your Epic account to access the repo.

  3. Offline package transfer for teams:

    • Mirror the Engine and project folders on a local file server or portable drive.
    • Share required Visual Studio toolchains and SDKs installers (DirectX SDK, Windows SDK) so the offline machine can compile and run UE4 projects.
