Epic Games designed the launcher to be your gatekeeper. There is no official "Download UE4.exe" button on their website. Why? Because the engine is modular. Between the core engine (50GB+), the Starter Content, the Templates, and the Platform Support (Android, iOS, Linux, HoloLens), a true "offline" installer would be a 100GB+ monolithic beast. Wait 20–40 minutes
