Cook failure, hint : missing UE4Game binary

I have installed visual studio 2015 and it work. When I cook my unreal project for windows by using UE4Editor, it hints:
Missing UE4Game binary.
You must use your IDE to compile the UE4 project, or , compile it by command line:

Meanwhile, when I packing the project for windows(both 32bit and 64bit), it hints Package cancellation before the packing process finished.
Both blueprint and code project have the same situation.
How can I do ?

Could you please upload your error output logs as a .txt file? Please upload them separately so that I can tell where one log ends and the next begins. :slight_smile: Also, please let me know whether or not you’re on a source or binary version of the engine. Did you get your engine from GitHub or Epic Games Launcher?
