Flash disabled vs Flash not installed

Ok I ran into a issue where customers are disbaling flash versus not having it installed (the player).

What is going on is in IE, they get a broken image but the script detects they have the plugin installed (which they do its just disabled). But when the plugin is not installed the script works fine and shows alternate content. Is there a detection script out the that detects if flash is disabled not just installed? btw I am using swfObject.

Please help, needed urgently. (searching google as we speak)
