The full instructions are here for anyone else encountering this issue. @Avi3ator, since you ran through steps 1-4 already when troubleshooting in a previous thread, you can start at step 5.
NOTE: This workaround only applies when your Engine install fails with error: ‘The necessary prerequisites have failed to install’.
- Manually download and install DirectX from here:
- Install [Microsoft Visual C++ 2010 Redistributable Package (x86)][2]. Also install [Microsoft Visual C++ 2010 Redistributable Package (x64)][3]
- Install [Visual C++ Redistributable for Visual Studio 2012][4]. Install both vcredist_x86.exe and vcredist_x64.exe.
- Install [Visual C++ Redistributable Packages for Visual Studio 2013][5]. Install both vcredist_x86.exe and vcredist_x64.exe.
- Install [Visual C++ Redistributable for Visual Studio 2015][7]. Install both vc_redist.x86.exe and vc_redist.x64.exe.
- Right click on your Epic Games Launcher desktop shortcut and select Properties. Under the Shortcuts tab, find the Target field and add this to the end of it(pictured below): -SkipBuildPatchPrereq
- Double click the desktop shortcut to start the launcher.
- Install the Unreal Engine.
- As soon as you have the engine installed, close the launcher and REMOVE the -SkipBuildPatchPrereq flag from your shortcut. Startup the launcher again.
