Development Platform & Builds

The exact notification I got on my computer is as follows: Assertion Failed: Result
[File:C:\UnrealEngine\Engine\Source\Developer\TargetPlatform\Private\TargetPlatformManagerModule.cpp] [Line: 497]

This will happen every time I attempt to launch any project with the version I use.

Reinstall Direct X.

The Editor requires PCD3D_SM5, shader model 5. Its not finding it because DX12 is not properly installed.

Reinstalling DX12 will fix this issue.
