When I package a game in UE4, it yields nothing!

I get nothing (no game or any files) when I package a game in UE4. I choose a location to save the packaged game, specify all the settings (icon, splashcreen, title etc) but after the game is finished uilding I go to the location to find nothing! Are there files I may be missing that are required to build games or what?
