I want to install Unreal Engine 4, which i got yesterday from a freind of mine.
But while building the engine from the sourcecode i get the following two errors:
We can only provide installation support for active subscribers who have downloaded the engine through either of our two official channels: the Unreal Engine Launcher, or the Epic Games repository on GitHub.
If you would like to use the Unreal Engine, I encourage you to visit https://www.unrealengine.com/ and subscribe for $19.00.
The source code is updated with each new release of the engine. If you’re getting the source from GitHub, which version of the engine are you trying to build?
