Vray for Rhino not working

[alda]

Hi,

I have rhino 5 and vray for rhino. I have used them both without a problem until recently. Now as I try to render nothing happens.

Vray is launched normally when I start rhino, when I click the option to render with vray I don?t get any message but nothing will happen. Nothing happens either when I try opening any of the vray features (material editor, lights, etc). It?s as if no command was given.

I have restarted the program and the computer, I've checked that the license is working and it all appears to be fine.

Any advice would be highly appreciated.

Many thanks!

Some times Windows updates destroy something. You could try to reinstall it.

Try:

- Check if V-Ray is chosen as renderer in "Render"->"Current renderer" and if it's enabled in "Render"->"Render properties"->"Plugins"
- reinstalling V-Ray and the license server
- Installing VC++ redistributables
2010 - https://www.microsoft.com/en-US/Down....aspx?id=14632
and
2015 - https://www.microsoft.com/en-us/down....aspx?id=52685

I've seen windows updates replacing 2015 with 2017 and that sometimes causes problems.

Did reinstalling the microsoft redistributables help?
