Missing UE4Game binary.
You may have to build the UE4 project with your IDE. Alternatively, build using UnrealBuildTool with the commandline:

Hey
Are you working within 4.7.6? If so, did you obtain the editor from the Epic Games Launcher or from GitHub? Can you please explain the error that you’re having when you’re trying to package your project? Could you also include the full error in a .txt file in your next reply?
Looking forward to hearing from you, thanks! 
Hi, thanks for your reply, I uesd my own version, inherited from 4.7.6，Downloaded from GitHub. We import our code in the “Engine\Plugins\Developer” and “Engine\Binaries\ThirdParty”. We are a company in china, VRGate, we are creating a device like Oculus Rift. Now I have solved the question, it seemed like my System problems. I Debugged the UE4 in Visual Studio 2013, it said “UE4 Editor not found”. I have a new question now, I can use my device in the editor when I click Play, but the device cann’t be used after packaging completed in the packaged file
Your project blueprint only? Afaik bluepring only project package do not work with plugins correctly.
Try to add some empty c++ object to your project and package again
It didn’t work, is there any package settings I forgetting to check or file I forgetting to import into the UE4 code ?
Hey
Did you use a guide when setting up your version of the Unreal Engine for GitHub? If so, did you use [this tutorial][1]? Also, how exactly are you trying to package your project? Is it through Unreal FrontEnd or is it through File > Package Project? When you added in your plugin, did you rebuild UE4 in Visual Studio?
Looking forward to hearing back from you, thanks!

Hi ,
Here is myalt text steps:
- Download the UE4.7 from GitHub.
- Open the “Setup” and “GenerateProjectFiles” items in the file, Downloaded from GitHub.
- Open Visual Studio and load the UE4 project.
- Import my owm plugins in “UnrealEngine-4.7\Engine\Plugins\Developer\VRGatePlugin” and “UnrealEngine-4.7\Engine\Binaries\ThirdParty\VRGate”. I create three BlueprintCallable functions to use, as a interface between Game and my Device. Then rebuild it.
- Debugging it and create a UE4 project,
- I can use my device in the unreal editor, and package it through File > Package Project.
- Open the packaged project, then my device doesn’t work.
Anther question, Are you a official programmer or developer in Epic Games? If so, may I have your email address for contacting ?

Hey
The error that you’re showing me is referring to your plugin that you’re using. If you go back through the comments, Detech makes a really good point that there could be trouble if you’re only using blueprints within your project. Have you tried adding C++ into your project to try and resolve the plugin issue?
Please try to build your project in either Development, Test or Shipping. Do not package your project for Editor configurations.
Steps to try:
- Make the project a code project (add a class like Detech suggested), and then enable the plugin in that project. Run GenerateProjectFiles.bat again, and then build the Development, Test, or Shipping configurations (whichever your packaging options are set to).
- In the plugin’s uplugin file, add the following line: “EnabledByDefault” : true
(see OculusRift.uplugin for an example). Then, run GenerateProjectFiles.bat again, and build Development, Test, or Shipping.
Please keep in mind that we do not support plugins that aren’t created by us. So if you’re using a plugin that was made elsewhere, you will need to contact that creator for additional information.
Also, are you able to show us what the error is when you actually launch the packaged game for VR?
Looking forward to hearing from you, thanks!
