Hello. Recently I’ve been trying to get into the Unreal Engine, having a few game ideas in mind I wanted to execute. However, while attempting to install the engine, I’ve been getting the same error each time I try to install it:
“Install Failed. The necessary prerequisites have failed to install. Error Code R-2147943860.”
I am not entirely sure what is causing this error, and it’s getting quite irritating. What can I do to fix this trouble?
Hello!

Also, could you please copy and paste the target line shown under the properties of your Epic Games launcher shortcut on your desktop?
Hello again. I’ve done what you asked and gathered up all the logs. You can find them below. As for the target line, here it is: “C:\Program Files\Epic Games\Launcher\Portal\Binaries\Win64\EpicGamesLauncher.exe”
Here are the logs: link text
