4.12 packed game crashes on startup


after solving my problems packing my game with 4.12 after updating from 4.11 I have the problem that I can’t launch the game. It always crashes with this message:

[2016.06.05-19.03.06:986][ 1]LogWindows:Error: === Critical error: ===
Assertion failed: ValA == 1 [File:D:\Build++UE4+Release-4.12+Compile\Sync\Engine\Source\Runtime\Core\Private\HAL\ConsoleManager.cpp] [Line: 575]

Is there any solution for this?
Thank you!

Hi KAEPS133,

I do not understand what you mean by “packing” your game. Do you mean “packaging” your game? If so, please respond with the following information:

  • Do you still have the original UE4.11 version?
  • Are you not able to open the UE4.12 packaged game or project itself?
  • Is that the entire crash log? If not, cut and paste the contents into a text file and post it here, it should include your machine ID.
  • Also, make sure you have hit “submit” at least once when the Crash Reporter pop-up asks you to, so that we can compare with similar crash report data.



Yes that’s what i meant.

I send the crash log several times, the problem was the log in the CrashReportClient was empty and the launch log in the \Saved\Logs folder just stoped at some point “render level” or something like that.

But I found the solution. I always ship the game as a setup installer and I create this on my own. I’m running a small console programm that adds my launcher and everything else. I’m also editing the config files and these changes are no longer compatible with UE 4.12. So I solved this by updating the config files.

Thanks for responding with what you did to resolve your problem in packaging your project. I’ve converted your comment to the Answer.
