Unreal Engine won't launch Error code (0xc000007b)

I install Unreal Engine but when I launch it, it said Application was unable to start properly. It seems I only get 64bits version of launcher.

I did thing with depends.exe

If u could check log.

Thank you.

Hi Nael,

What you’re seeing is a general error that can occur with any install process. Make sure you have latest DirectX and .NET Framework. You may also need to reinstall these if updating does not fix issue.

Once they are updated, if issue is still happening; try excepted answer in ].

Hi TJ Ballard,

I tried and still don’t work…
Hope u can help me.

Could you follow steps here and generate your Debug Logs, then post them here? They are different than logs you posted above.

Also, post your Dxdiag (system specs) as well.

I dont know why but folder with Debug Logs dont want to creat…

I have just dxdiag…

To manually locate this folder go to this location on Windows.

C:\Users\UserName\AppData\Local\EpicGamesLauncher\Saved\Logs. Here you will be able to see all log files generated for Launcher. Grab your dxdiag and most recent log from your crash and them into a folder. Then you can attach it to your response here on AnswerHub.

Let me know if you are still having trouble.
