After the most recent update, trying to open any uproject file associated with UnrealVersionSelector.exe results in ‘Failed to launch editor’.
Using Process Monitor I can see that it is looking for UnrealEditor.exe in the Binaries/Win64 folder when it should be looking for UE4Editor.exe
Hey! Thanks for the information you shared. We’ve been having the same issue since yesterday night, I guess after an Epic Launcher or Unreal update.
We fixed it by renaming the “UE4Editor.exe” to “UnrealEditor.exe” in our Program Files\Epic Games\UE_4.23\Engine\Binaries\Win64.
It looks like the update broke the link between UnrealVersionSelector.exe and UE4Editor.exe because it is not looking for the editor app under the right name…
At this point, either we’re not understanding something right, or the last update wasn’t verified properly before being pushed by Epic.
In any case, so far so good, hopefully nothing else is broken with this.
Cheers!
