title: Detecting if flash is installed using SWFObject
body: <p>I was googling for about half an hour and I couldnt find any useful information to do this, I only found out that expressInstall.swf applies when you have a lower version of flash, but at least you have one installed.</p>
  
  <p>So, long story short, how do I do to detect if I have Flash installed on my PC using SWFObject.embedSwf ?, and what I want to do is, that if I dont have it installed, to show me some custom content. </p>
  
  <p>Is this possible using SWFObject?</p>
  
  <p>Thanks.</p>
