How to detect plug-ins path for Photoshop CC?

Hi

I downloaded new CC SDK but unfortunatelly in html doc there is not info how to detect a plug-in path for new Photoshop CC. Pdf doc also contains very old info (still for Photoshop 5.0)

- Could you advice how my installers can detect new Photoshop CC and detect a target place for plug-in installation? Forboth  win and Mac cases.

- Is CC a pure 64bit windows app or it also can be presented into both C:\Program files and C:\Program files(x86) folders?

Thanks

Maxim
