Ok, i found a solution for those they have the followed issue : Launcher not launching --’ and missing binaries (Win64) you have to go to Epic Games/Launcher/Portal/Binaries
Copy and Past the Win32 folder, rename it into Win64 go in this new folder, run EpicGamesLauncher.exe as administrator, he will launch and do an update and create you the Win64 binaries folder in Engine path, here you go, you now have an Epic Games Launcher working, you’re welcome
