Hey EduHenrique,

Thank you for providing us with your logs. I was wondering if there were any additional information or output logs that you’d be able to provide? Per perhaps these logs: “See logfile for details: ‘UnrealBuildTool.txt’”.

Any additional information is greatly appreciated.


Hello Samantha Sutton,
Thanks for the reply
I finally package my project. its an target error. for some reaction, the unreal not find the Includes in my c++ codes. and i need to put manually.
But i cannot start my project.exe
I receive the error : 0xc000007b

Hey EduHenrique,

When you say you can’t start your project, are you provided any logs with that? Do you think that you could put -log at the end of your target line in your executable to obtain some logs for us? The more information that we have, the easier it’ll be to pin down what the issue is.

Thank you!

they give me no logs. even with -log

Hey EduHerique,

Inside of your .exe folder that’s created for your packaged project, do you have the following folders: WindowsNoEditor\MyProject\Saved\Logs

You should be looking for ‘Saved’ and then ‘Logs’. There should be logs placed in that folder, which will be helpful for the developers to review.

Also, with the error that you receive: 0xc000007b; that seems to happen to people when they’re opening the Editor. I want to verify that this happens to you when you try and open the executable packaged project, am I right?

Looking forward to hearing back from you, thanks!

yeah. this happens when i try to open packaged project. And in WindowsNoEditor\MyProject i have only 2 folder Binaries and Content wish have an .exe and a .pak file.

Hey EduHenrique,

Are you able to upload your packaged project to an external site and provide me a way to download it? Or perhaps, are you able to provide me with the project so I can package it and see if I receive the same result? We need full logs in order to be able to figure out where the issue is and how to resolve it, and without those, the project would be the next thing we’d need.

Let me know what you’re able to do. If you can provide full logs, please upload them and I’ll take a peek.

Thank you!!
