Hi ,
Is the desktop shortcut you are launching UnrealEngineLauncher.exe or UE4Editor.exe? Thank you!
When I run the ud4e 64bit closes but had already happened to me in CryEngine 3 is only running it in 32-bit but the unreal engine 4 empty tine Folder 32 bits only have the 64-bit where to keep the 32 or and solve the problem that I call the program does not end.
Did not quite understand your answer but if you mean as I ran I entered the folder unreal engine 4’s to engine then binaries for win64 and there run the UE4Editor but the problem was get on the carpetra of win64 as CryEngine 3 could not open it in win64 but wan32 or closed the same as me going on the unreal engine 4, but the unreal win 64 folder is empty and no tien any executable or just a freak. dll file but does not serve me I can do where I get the win32 you have it in your folder unreal engine 4 if so could you pass me the sb or the need to see this comment thanks for answering what you agradesco .
certainly not to find any UnrealEngineLauncher.exe where I find this or that direction. 
With a valid install of UE4, the launcher install is here:
C:\Program Files\Unreal Engine\Launcher\Engine\Binaries\Win64\UnrealEngineLauncher.exe
In order to use the Launcher and properly access UE4, you must have created a paid subscription account on UnrealEngine.com. Once you have this, you can download the Launcher from your account page, which once installed will then download and install the UE4Editor.
We can only offer installation & setup support for users accessing the editor from the Launcher or from our GitHub repository.
Have a good day!
