Real DWG 2014?

I need to use the AutoCAD Civil 2014 Object Enabler for some C3D files I received, but when I install it, it says it can't find any compatible software (or something like that). From what I understand it is because I need to install RealDWG 2014. Where can I download this from? I can only find RealDWG 2016 on the fulfillment center.

Or can I effectively get 2014 simply by setting the configuration variable MS_REALDWG_VERSION to 2014?

MS SS4 v08.11.09.832
