Note to myself: Not so fast!
I was mistaken, what I saw was not a special Vienne Ensemble VST3 dll but a none-dll that must serve some other purpose in VST 3 communication. So I'm back to square one, but I know from the picture shared by DG that what I want to see is possible. And I'm noticing some language in the Vienna Instruments manual that refers to the accompanying installation of Vienna Ensemble as VST3 compatible and makes it sound like no special installation option is needed.
So there's still something (in Cubase 7 I suspect) that is preventing things from looking my project like it does in DG's.
