Hello,
I downloaded UE 4.6 yesterday. When i press launch button nothing happens. What should i do?
Normally a window, where you can choose the project, should appear (this can take a while) → after you have pressed launch, open the task manager and check if you can see a UnrealEngineEditor in the process tab. Have you already tried to open the engine with the uproject file in one of your projects? Also make sure that you open the launcher with admin rights.
actually uproject files is not actually telling me which program will it open with. Select program from list occurs. Just now i found where editor exe is so i launched it from there. But i cant launch it from launcher.
Take a look at this thread, probably it will solve your problem: Unreal engine 4.1.0 won't start from Launcher, windows 7 - Platform & Builds - Epic Developer Community Forums “We believe this issue is most likely caused by your Windows username having a non-ascii character in it.”
That means ill have to use it manually until the buy is fixed.
