Is there anyway to download the Unreal Engine 4.27 on a USB? So I can install it on a desktop without internet access?
Hey @chunter281 !
Unfortunately, Unreal Engine doesn’t have an offline installer for customers to use. To install Unreal Engine, you must first download and install the Epic Games Launcher, or use the option of building from source. A base .exe file just does not exist, unfortunately. 
Hope that at least gives you a path forward!
