Launcher doesn't start!

Hi, I’m trying to use Unreal Engine.

  1. At first, I installed EpicGames Launcher.
  2. Click the Launcher and Launcher start to download something. (start with admin authority)
  3. After downloading, It verified itself. and start to install necessary programs.
  4. Launcher was gone.
  5. Try to start Launcher → I got error. “0xc00007b” (start with admin authority)

That’s my Problem. And you should know

  1. I already installed Microsoft Visual C++ Redistributable 2005/2008/2010/2012/2013/2015 (x64, x86 both)
  2. DirectX is up-to-date. DirectX 12.
  3. I was reinstalled Graphic Card Driver. (Intel Graphics / NVIDIA GTX 970M)
  4. I am using Windows 10 64bit OS.
  5. I have DWalker Log, DirectX Log. Attached → Log File Download

Resolved! From DWalker Log, I Found that I have DirectX Problem. So, Delete C:\Windows\System32\xinput1_3.dll and C:\Windows\SysWOW64\xinput1_3.dll. and Reinstall DirectX. Rebooting. Success to start Launcher!
