Hello.
I have a question about AIR Runtime beta 15.0.0.302.
Download Adobe AIR 15 Beta - Adobe Labs
Download runtime from the above site.
Version that you downloaded was 15.0.0.297.
Where can I get AIR Runtime beta 15.0.0.302?
That looks like the AIR desktop installer. Build 302 is the version for the AIR SDK download. It's the second set of links on that page.
The Runtime(PC) latest version 15.0.0.297?
Runtime(PC) 15.0.0.302 does not exist ?
Yes, I think that's right. The fixes in 302 were urgent ones needed to work around changes in the Apple submission process, and other iOS 8 related problems.
