Editor crashes on launch (Ver. 4.3)
Howdy Stackazzii,
Thank you for reporting this issue. Would you be able share your DXdiag and your log Editor log files on the issue? Any additional information about the crash would be greatly appreciated (ex: Have you had UE4 previous to this crash,…). This will help us with investigating the issue.
Your log files can be found here: Windows: C:\Users\USER.NAME\AppData\Local\UnrealEngineLauncher\Saved\Logs
Thanks and have a great day!
I am not sure if i am missing it or not, but what GPU are you using?
Nevermind, I see them in the log files.
Hey Stickazzii,
Just a couple more questions that could help diagnose the issue. Have you been able to use the Editor prior to the 4.3 update? Also, have you attempted to uninstall and then re-install UE4?
Here are a few workarounds that may be helpful: A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums
Thanks!
Never been able to use the editer in any versions.
And I tried to re-install.
Thank you, Sean Gribbin for fast answers and being helpful! 
Have a nice day!
Hey Stickazzii,
In order to use the Launcher and properly access UE4, you must have created a paid subscription account on UnrealEngine.com. Once you have this, you can download the Launcher from your account page, which once installed will then download and install the UE4Editor.
We can only offer installation & setup support for users accessing the editor from the Launcher or from our GitHub repository.
Have a good day!
