Kontakt VST3 support

How does Dorico know where to locate the Kontakt 6.7.1 VST3?

I ask because Native Instruments asked me to send a screen shot of the VST setup but Dorico 4.0.31 seems to only show VST2 paths.

Is it a simple matter that VST3 plugins all go in

C:\Program Files\Common Files\VST3

whereas VST2 plugins could go in any of several conventional locations? I was not able to find a definitive answer to this so far in the internet. [I suppose I should find the VST3 specification.]

You are right, the mentioned path or any subfolder in there is the place for VST3 plug-ins.
