Adobe Air 18 on OSX 10.10.4 (Yosemite)

I installed Adobe Air 18 on MacBook Pro 13 (Retina display) with OSX 10.10.4

Installation seems ok but when I try to open myfile.air with "OpenWith" finder option I can't see Adobe Air in the applications list.

Also I can't find Adobe Air in the Applications folder

regards.
