V-ray for rhino won't start

Hello Guys,

I tried everything that you tried but still V-ray is not working …
The rendering won’t start, I have the window where I can select my material but when I clik on “render” nothing happen …

I was looking for the QTCore4.dll and QtGui4.dll in the windows/system 32 but could not find them … However I found them into Rhino and solidworks program files … should I delete them ?

I Already tried to unstall and reinstall Rhino and V ray, instal all the different version of Visual C++, add the different plug in as Scarlov87 said but still Vray is not working …

If someone has an other idea which can help I would be grateful !:pray:
