airSWF.getApplicationVersion not working in Chrome

airSWF.getApplicationVersion(appID, pubID, versionDetectCallback); works fine in latest versions of Edge, Internet Explorer and Firefox with latest version of Flash Player and returns the link to the requested application so that it can then be opened from a mouse click in the browser - airSWF.launchApplication(appID, pubID, arguments);. When called from the latest version of the Chrome browser however, it always returns null.

Does anyone know if there is any solution to this problem?
