VS 2015 (compile error) Editor.uhtmanifest UE 4.12.5

Development Programming & Scripting C++

Hello there,
I know there’s lots of information, so I’ll put this into point form for ease of reading. I appreciate any help.
Win 8.1
VS 2015 community Edition.
Trying to compile in game - gives me these errors.

Info Failed to read makefile: Exception has been thrown by the target of an invocation.
Info Creating makefile for hot reloading Dusty (couldn’t read existing makefile)
Info Compiling game modules for hot reload
Info Performing full C++ include scan (no include cache file)

Project Compiles fine for two other people.
VS is up to date.

VS upon a clean / build - shows the following ( in developer mode )

I am not sure what is causing this issue. I have run both UE4, and VS as administrator. Any help is appreciated.
Thank you.

The error is here:

It’s complaining that it doesn’t know what a UUserWidget is. Try adding "include “Blueprint/UserWidget.h” " to the top of your DustyGameMode.h and see if that fixes it.

EDIT: Also, make sure you re-generate your VS Solution, someone may have recently added a new dependency. Just right click on your <Game>.uproject file and select “Generate Visual Studio project files”.

Hi @ExtraLifeMatt. Thank you for the reply.

#include “Blueprint/UserWidget.h” Is already located in DustyGameMode.h. I have also already tried to “Generate Visual Studio project files” without success previously.
Unfortunately I’m still stuck.

Hmm. Have your checked your <MyGame>.Build.cs file and made sure UMG is in the dependency list?

That + Generate VS Project files (with the include in that file) should be all you need.

@ExtraLifeMatt You sir are awesome. Thank you very much.
The issue was that I did not have “UMG” in the dependency list. Once I added it, I regenerated the VS project files and voila. Compile Complete.
