1. Go to the place where you've installed launcher (usually c:\Program Files (x86)\Epic Games\)

2. Open the 'DirectXRedist' folder

3. Inside, there will be several .cab files (those are just simple archives)

4. Open those .cab files and extract JUST the .dll files, and put the wherever you want (could be the Desktop)

5. Now put those .dll files that you extracted inside the folder where your launcher is located (usually c:\Program Files (x86)\Epic Games\Launcher\Portal\Binaries\Win32\)

6. Launch the Epic Games Launcher and you should be good.
