Unreal Engine 4.8.3 won't launch

If I click on the yellow Launch button it goes gray and after a few seconds does nothing…
Sometimes It loads and when it gets to 96% it crashes…
I re-installed it a few times
What can I do?

Hi TREDX,

Could you post your Dxdiag (system specs), Crash Logs, and Dmp files? You can find info on where to find all this here.

Hi TREDX,

We haven’t heard back from you in a few days, so we are marking this post as resolved for tracking purposes. If you’re still experiencing this issue, please feel free to post back here with additional information.

Cheers,

TJ
