Impossible to run vray in rhino 5

I’ve installed rhino 5 90 day free trial and also the vray trial for rhino 5. The vray installation is fine but It doesn’t appear when I open Rhino. I’ve tried to reset the toolbar, but nothing happens.

The message that is shown : Loading Rhino Render, version 1.50, May 22 2017, 09:16:00

Thank you

Try to select Render menu and set the v-ray current render engine.
