The badge installation stopped working recently, probably after last Google Chrome update. Problem look 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 11.3.31.222

AIR 3.3.0.3670

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.

There is a cumbersome workaround but it does clearly show that this is a PPAPI (pepper) related issue.

1. Navigate to "about:plugins" in the Chrome address bar
2. Click the Details link in the upper right part of the page to expand all items
3. Locate the "Shockwave Flash" entries (there will be 2 or 3 of these)
4. Click "Disable" for the PPAPI copy (most likely the first one listed), which has a version number of 11.3.31.222
5. Restart Chrome for good measure and try again
