Mentalray plugin failure

[b]In the maya plugin manager,

I was able to see the mentalray plugin option,
[/b]
but when I tried to launch the plugin, there was an “error: file: D:/Autodesk/Maya2018/scripts/others/pluginWin.mel line 290: Cannot load dynamically: C:/Program Files/NVIDIA Corporation/mentalray 3.14 for Maya 2018/plug-ins/Mayatomr.mll”(Cannot find the specified program)and “Error: file: D:/Autodesk/Maya2018/scripts/others/pluginWin.mel line 290: Cannot find the specified program. (Mayatomr)”

Please ask mental ray questions on the dedicated user forums you can find here: https://forum.nvidia-arc.com/
