Hello, i have sketchup 2017 Pro License. Is it possible to use it for Sketchup 2016?  
I need to downgrade to use Vray. When i try to add license, it say that my serial is wrong for sketchup 2016.  
Thank you.

license data is (unfortunately) valid for the main version issued for only, i.e. license data of SUP 2017 doesn’t work with any other/older version.

Contact your buying source and ask for SUP 2016 license data, if bought by Trimble directly [here](http://help.sketchup.com/en/contact).
