Just in case this will help anyone,
When trying to load the female soldier I received an error that Arnold was not installed.
Arnold is a Renderer from Autodesk, and it IS actually installed, but does not seem activated on my Student version (Maya 2017).
The help desk says it's supposed to be in this directory;
C:\Program Files\Common Files\Autodesk Shared\Modules\Maya\2017
But my folder is COMPLETELY empty.
You can try reinstalling Maya, or go here
and install Arnold.
(You'll need to register an account, before it downloads.)
The install directions for windows are here
, and about halfway down it explains how to enable it in Maya.
