Error loading plugin library

[AliKoo]

Hi !

I have just installed V-ray for Revit 2017, the trial version . When I run render RT the following error appears everytime :
[Error] V-Ray: Error loading plugin library "C:\Program Files\Chaos Group\V-Ray\V-Ray for Revit\libraries\vrayappsdk\bin\rt_cuda.dll": LoadLibrary failed (126): Nie można odnaleźć określonego modułu.

In the Warning window I find the folllwing warning : [Warning] V-Ray: Failed to load CUDA renderer plugin from "C:\Program Files\Chaos Group\V-Ray\V-Ray for Revit\libraries/vrayappsdk/bin/rt_cuda.dll" [Warning] V-Ray: Failed to create CUDA renderer plugin instance.

I dont even know how this affect my render because I am new to V-ray but I guess it might be a major problem. I reinstalled the program but the message still appeares. Have no clue what to do.

Kindly asking for help !

Update your Nvidia graphics card drivers.
http://www.nvidia.com/Download/index.aspx
It looks like you are running RT in GPU mode, and V-Ray will throw up this error when your drivers are out of date.
If you do not use an Nvidia graphics card, then you will need to turn GPU off so RT will use your CPU as we only support Nvidia graphics cards at this time.

Hope this helps!
