Flash Player detection is available only for publish settings set to Flash Player 4 or later, and for SWF files embedded in the Flash Only or Flash HTTPS templates.
To detect the presence of Flash Player before allowing a browser to view SWF files that use the following templates, create a separate HTML page with its own SWF file to detect Flash Player before redirecting browsers to the HTML page that contains the Flash content.
The following HTML templates do not support Flash Player detection because the JavaScript in these templates conflicts with the JavaScript used to detect the Flash Player:
Flash for PocketPC 2003
Flash with AICC Tracking
Flash with FSCommand
Flash with Named Anchors
Flash with SCORM Tracking
