Intallation now comes with installers for Beta11. The directory it will install to is the standard NVIDIA Corporation directory. It will also change the Autodesk system mentalray.mod file, so the plugin should work without manual intervention. The installer beta plugin comes in .run form for Linux and .exe for Windows, and .dmg for Mac OS X.
Now, this new installer changes the mentalray.mod file located in the respective version folder on Windows:
C:\Program Files\Common Files\Autodesk Shared\Modules\Maya\2016\
C:\Program Files\Common Files\Autodesk Shared\Modules\Maya\2016.5\
C:\Program Files\Common Files\Autodesk Shared\Modules\Maya\2017\
Remove the mentalray.mod files from betas previous to beta8 in this directory:
This is a directory Maya knows to look at to override the previously installed module. It is how we do earlier betas, but not ones close to release with installer packages.
