Epicgamelauncher.exe got deleted?

So i installed epic game engine and was using it fine for a day or two, but today when i switch on my pc, i noticed my desktop shortcut is a blank, and when i click it, it tells me it cant find original Epicgamelauncher.exe.(the UE4 folder is still there but it see only the Epicgamelauncher.exe is deleted for some reason). is there anyway where i can repair the UE4 or fix it without downloading and installing the whole thing again?

i tried runing the installer again but it only have the option of uninstalling

win10/I5-2500K/GTX970/8Gig ram.

Can you check the Portal sub folder to see if you have an EpicGamesLauncher.exe there?

nop, not in there, in portal folder, there is only a services folder which as Private/Public folder and PortalServices.Build.cs.

no idea why or how it got delete though.

can you upload a launcher exe so i can just place it there?

I think you are checking the incorrect folder so let me see if I can clear things up:

If you installed to the default folder, launcher executables live in these two folders:

C:\Program Files\Epic Games\Launcher\Engine\Binaries\Win64
C:\Program Files\Epic Games\Launcher\Portal\Binaries\Win64

Can you tell me the contents of those two folders?

i check every folder and done search on the epic folder but found nothing.
i fixed the problem by reinstalling. seems like i dont have to download again because the installation folder is still somewhere on my pc
