Hello,

I’m currently running Max 2015 I just installed Max 2018. I would prefer not to uninstall 2015 and the related plug-ins until I get 2018 up and running without issues,  
Can I install Vray on Max 2018 without uninstalling 2015 and run both programs from the same dongle?

Thank you.

Hi,

Yes you can install and use more then one Max version if you want on the local workstation.  
One GUI license for an example allows you to use V-Ray on one machine without limiting the Max/V-Ray sessions opened. The same is for the render node license.
