Hi,
we have created a new build of the NVIDIA Mental Ray for Maya plugin, version 1.2.1. The primary purpose of this update is to fix a problem with the original installer, which stopped working with latest NVIDIA driver installers on Windows. At the same time, we also addressed few minor issues in the plugin itself, and in the Mental Ray core engine.
You can download the new version from our Mental Ray for Maya Forum for Linux, Windows, and Mac. This update is not auto-distributed through the NVIDIA Professional Application Center this time.
We would appreciate if you let us know that it works for you.
Happy rendering!
Inside mental ray 
Good day. May i ask if I can get a mental ray license so I can batch rendered my projects. Mental ray has been my rendering tool all my life and I will not trade it for anything else. Oh please 😦
Hey, just write an email with your request to the licensing team.
Hello. Does Mental Ray Standalone for Maya 2016 require a GPU? I purchased a renderPro 2 to offload my render jobs and I’m having a heck of a time getting it going. I wonder if I’ve installed the wrong version.
If you purchased a ProGPU license you need a GPU to activate Mental Ray. If you don’t have a supported GPU you need a regular license.
