The badge installation stopped working recently, probably after last Google Chrome update. Problem looks like this: after clicking "install now" badge the confirmation window to install Adobe AIR appears ("Would you like to install adobe AIR?"). I click yes, download progress bar goes from 0 to 100%, and then error message appears ("Download error. Try again?"). Click yes - everything repeats.
Also, in Chrome on Windows there is text under the badge: "In order to run <app name>, this installer will also set up Adobe AIR" - but latest AIR is already installed. We used standard installation badge, provided with the SDK.
OS Windows 7 ver 6.1 (build 7600)
Browser Google Chrome 21.0.1180.60 m
Flash Player 188.8.131.52
The problem appears only in Google Chrome, and only on Windows. In IE and FF everything seems to work fine. In Chrome 21.0.1180.57 on Mac OS X 10.7.2 it works fine as well.
