Ue4prereqsetup-x64.exe ~repack~ -

When you launch the game for the first time via its official launcher (Steam, Epic Games Store, GOG), the launcher often executes ue4prereqsetup-x64.exe silently in the background. If you have ever seen a small command prompt window flash for a second before the game boots—that was this tool. If you downloaded Unreal Engine 4 from Epic’s GitHub repository (back when it was publicly accessible) or are using a custom build, the file resides in:

[UE4 Install Path]\Engine\Extras\Redist\ ue4prereqsetup-x64.exe
