"Close programs to prevent information loss" dialogue during V-Ray Render

Rendering V-Ray

Hi All,

I am trying to render a scene with V-Ray Rhino (64 bit) at 2000 x 700 Pixels, but I would get the “Close programs to prevent information loss” dialogue box. However, I can render images at much lower resolutions with no problem. I am running a Mac Pro with Windows 10 through Bootcamp, with 32 GB Ram.

Any help would be very much appreciated.

Thanks!
