Sounds like there was some error when installing the engine. Through the Epic Games Launcher you can Verify your installation of the engine, try that or re-install it.
谢谢！我在EPIC客户端没找到修复或是重新安装引擎的选项，另外我在公司和家里的两台电脑安装引擎后都出现了相同的问题，感觉应该不是安装过程有问题。
好的，所以我搜索了该错误消息，这似乎是较旧的Windows版本Windows 7和8上的问题。尝试在Windows 10上使用。

Windows 7 machines give dxgi.dll error on UE4 startup with OSVR-Unreal enabled, … even though dxgi.dll is present on the machine.
Machine that worked: dxgi.dll version 10.0.10586.494 modified 6/30/2016, Windows 10
Machine with error: dxgi.dll version 6.2.9200.16492 modified 1/13/2013, Windows 7 with Platform Update installed
UE4 and our full game builds work on the same machine fine without the error if OSVR-Plugin is not present or disabled. Other UE4 VR plugins enabled do not give the error on same machine.
I'm guessing the OSVR SDK binaries were built and linked against the newer dxgi.dll . From a quick grep, I suspect osvrRenderManager.dll or SDL2.dll .
