Completely stuck no matter what I do, I get this error message every single time.
I have tried :
-OpenGL
-http=wininet
Uninstall and reinstall
Opening several ports (5222 and the likes)
Nothing is working, emails don’t get responded to, and no solution on the internet has proved useful at all.
If ANYONE at Epic Games would help, I would be very thankful, or anyone that knows how to fix this annoying issue causing me to not be able to play anything at all.
Hey Moreo,
Have you tried checking to see if you have a weak internet connection?
Also, if you are urgently needing to work on a project, you can launch the UE4 project without needing to use the Epic Games launcher I believe. Go to the folder the project is saved in and double click on the (.UnrealProject) File.
Hope this helps! 
I have a near perfect internet connection, and prior to about 3 days ago, I had no problems loading the launcher. I kid you not, I woke up one morning and the launcher didn’t work anymore. At this point its more annoying that there is no solutions out there and EpicGames hasn’t helped at all.
It could be a glitch. I would just hold tight, I’m sure they will get back with you and run a patch on it sooner then later.
It looks like other users are experiencing this same issue
See if this may solve your problem with the launcher EpicGamesLauncher (0xc000007b) - Getting Started & Setup - Epic Developer Community Forums
Hope it helps
Yes, same thing has been happening to me for years. I try every once and a while but never gets better. I honestly don’t think they are even aware of this bug.
