Help finding Omnisphere in Logic Pro

New Macbook Pro with external 1TB drive. No issues with Synthology Ivory 2 except having to open Logic in 32 bit mode first to have it recognized. With Omnisphere I suspect an install issue. Loaded everything on to an external drive however not in one folder. So on the drive I have a folder for Synthology called Ivory Items and then what looks like 4 folders created by Omnisphere -

1. Application Support

2. Audio

3. Library

4. STEAM

I think I was supposed to place these 4 folders in a named folder I should have created called (example) Spectrasonics. Tried this as well but in either instance I can't find or launch Omnisphere from Logic, It is not listed in the AU Instruments at all. I see Synthology but nothing else. Help please.
