Development Getting Started & Setup

Hi there,

I am having an issue since this morning with my unreal launcher.
I reverted a commit on my github and since then, when I try to launch UE4.10.4 from the epic games launcher I get this message :
“Failed to Launch
Could not launche Unreal Engine. Please verify the installation.”

verifying the installation did not solve my problem at all. Actually after verifying and rebooting my computer I had a desktop display issue that I managed to solve.
I tried deleting the launcher manifest but nothing seems to be able to solve my issue …
Here is my launcher log file.

I’m accepting the answer for now for tracking purposes. However, if you still cannot launch UE 4.10 after following the troubleshooting steps on the link above, respond to this thread and we will continue to investigate.

I still cannot launch UE4.10.4
I sent an email to the launcher support with my launcher log file and I am waiting for an answer now.

Launcher Support should respond shortly. In the meantime, if present, you can bypass the Launcher and try and open “UE4Editor.exe” directly from the binaries folder located in your install directory.
