Mental ray not working in maya 2016 Dec. 10, 2018, 4:37 p.m.

When I try to load the MentalRay plugin with Houdini installed, this message appears:
// Error: file: CProgram Files/Autodesk/Maya2018/scripts/others/pluginWin.mel line 290: The specified procedure could not be found.
(Mayatomr)

I found out that the problem is a DLL File with the SAME NAME in Houdini and MentalRay.

libRAY.dll (C:\Program Files\Side Effects Software\Houdini 17.0.352\bin\libRAY.dll)
libray.dll (C:\Program Files\NVIDIA Corporation\mentalray 3.14 for Maya 2018\bin\libray.dll)

When I rename the DLL in the Houdini Folder, MentalRay works perfectly, but Houdini doesn't anymore.
When I leave the DLL in Houdini, Houdini is working good, but Maya cannot load the MentalRay Plugin.

The issue is having the same name DLL file on my Windows system. No other issue is present except this DLL issue. If there is a way to point to the MAYA dll when loading MentalRay, then it might work. Seems like when Maya is loading the DLL, it is trying to load the DLL from Houdini. Strange. Somone must come up with a solution…
