I used Adobe s detection kit  originally suggested by justpassinby  Their system is nice because it detects the version number and compares it for you against your  required version   One bad thing is it does an alert showing the detected version of flash  which isn t very user friendly  All of a sudden a box pops up with some seemingly random numbers   Some modifications you might want to consider    remove the alert change it so it returns an object  or array  --- first element is boolean true false for  was the required version found on user s machine  --- second element is the actual version number found on user s machine

If swfobject won t suffice  or you need to create something a little more bespoke  try this   var hasFlash   false  try       hasFlash   Boolean new ActiveXObject  ShockwaveFlash ShockwaveFlash       catch exception        hasFlash     undefined     typeof navigator mimeTypes  application x-shockwave-flash         It works with 7 and 8
