Hi sportguitarRC,
I noticed that there are some special characters in the file path for the location where you are trying to build the Engine (Rafaël Côté). There is an issue that is internal to Visual Studio where having a special character anywhere in the file path can prevent the Engine, or a game project, from building successfully. It has to do with the way that Visual Studio communicates those characters to the Unreal Build Tool.
Could you please try building the Engine in a location where there are no special characters in the file path, such as C:\Unreal Engine 4\?
