Hi,

I’m trying to launch my Unreal Game on Windows. It works fine on Android and iOS.
My scenario:
Clicking “Launch” in top of editor and trying to launch it on my Windows PC.
I’m getting this error Message:

ERROR: System.IO.DirectoryNotFoundException: Ein Teil des Pfades “D:[ProjectName]\Intermediate\Build\Win64\ [ProjectName]\Development\Launch\Launch.precompiled” konnte nicht gefunden werden.

Which means: Unreal cannot find the file “Launch.precompiled” for my launch. And yes, it’s true, the file isn’t there. How do I get this work?

Packaging also doesn’t work.

Thanks in advance

Hey , I ran into the same problem today. Did you ever find a solution? (German is ok too, if it floats your boat)

To anyone having the same problem: Currently (UE4.20.3 2018-10-09) there seems to be an engine bug not allowing you to use a Unique Build Environment on prebuilt engine binaries unless the project is in a subdirectory of your engine.
