I understand you're looking for an offline installer for Unreal Engine 4. However, I should clarify a few important points:

Unreal Engine 4 is no longer directly available for new users from Epic Games. Epic has moved to Unreal Engine 5 as their primary supported version. UE4 is now a legacy product, and Epic no longer provides official standalone offline installers for it.

What you can do instead:

  1. Download Unreal Engine 5 (free) – Use the Epic Games Launcher, which is required even for offline installation. The launcher downloads the engine files, after which you can use them offline.

  2. For UE4 specifically – If you have an existing Epic account that previously had UE4 licensed, you might still access older UE4 versions through the launcher’s library. There is no official standalone offline installer distributed publicly.

  3. GitHub access – Epic previously made UE4 source code available to verified developers via GitHub, but that program now focuses on UE5.

Warning: Be extremely cautious of third-party websites offering "UE4 offline installer" downloads. These are often:

Recommended legitimate path: Download the Epic Games Launcher from Epic's official website, install it, then download UE5 (or any accessible UE4 versions) through the launcher. After installation, you can set the launcher to offline mode and continue using the engine without an internet connection. Unreal Engine 4 (UE4) is free to download for everyone

If you specifically need UE4 for compatibility with an existing project, I recommend checking your Epic Games account library or contacting Epic support directly.

Step 1: Download the Epic Games Launcher

Go to the official Unreal Engine website and download the launcher. Install it on a machine with internet access.

Why Doesn’t Epic Provide an Official Offline Installer?

Epic Games designed UE4 with continuous integration in mind. The engine receives frequent updates, hotfixes, and binary patches. A static offline installer would:

Instead, Epic relies on the launcher to manage versions, downloads, and incremental updates efficiently.

3. Can’t Open Existing Projects

Project files (.uproject) store engine associations. Right-click the .uproject → "Switch Unreal Engine version" → "Browse" → point to your offline engine’s Engine\Binaries\Win64\UnrealVersionSelector.exe. Download Unreal Engine 5 (free) – Use the

How to Create an Offline Installer (The Workaround)

If you need to install UE4 on a computer without internet access, or if you want to install it on multiple computers without re-downloading 40GB every time, you must use the Backup method.

Here is the step-by-step process to create your own offline installer package:

  1. Install on an Online Machine: First, download and install the specific version of UE4 you need on a computer with a stable internet connection via the Epic Games Launcher.
  2. Locate the Files: Navigate to your installation directory (usually C:\Program Files\Epic Games\UE_[Version]).
  3. Create a Backup:
    • Open the Epic Games Launcher.
    • Go to Library.
    • Click the small arrow next to the "Launch" button for your installed engine version.
    • Select Create Backup.
    • Choose a location (like an external hard drive) to save the backup file.
  4. Deploy Offline:
    • Move the backup file to the offline computer.
    • Install the Epic Games Launcher on the offline machine (a small file you can transfer via USB).
    • In the Launcher, click "Install" on the engine tab, but point the directory to where you want to restore.
    • Alternatively, you can simply copy the entire game folder to the new computer, though using the Launcher's restore function is cleaner.
