Turns out there was a folder that contains VST versions of everything NI that I own & RB can use them .. I was just rushing and didn't look everywhere.

They were all in a folder located here -
C:\Program Files\Native Instruments\VSTPlugins 64 bit

hoodathunk that folder was the key ingredient <embarrassed>
Now all my NI stuff loads in RB as expected.

Hope that helps someone besides me smile

I do not work here, but the benefits are still awesome
