THIS IS NOT A REPOST!
I get this error when i try to install the Unreal Editor!
In your %Temp% folder you’ll find some logs that start with UE4_Prerequisites. To access this folder simply type %Temp% into the Windows File Explorer file path bar. Zip those files up, attach to the thread, and I’ll have a look. Judging by your previous post, I suspect we’ll find that DirectX is having an issue installing again. If that is the case, we’ll have to apply a workaround somewhat similar to the one you used to get the Launcher installed. I’ll work on getting the steps for that workaround drafted up while I waiting on your logs.
As suspected, DirectX is not installing properly. Here are the interesting bits out of your install log:
Installing DirectX.
DXSetup exited with code: -9
Failed to install DirectX.
CustomAction CAInstallDirectX returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)
Will post up a workaround shortly.
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.
I’m still actively trying to track down the reason some users encounter the code -9 DirectX error. It would be incredibly helpful if you could attach your DirectX.log files. They are usually found here: C:\Windows\Logs
