First of all it's really simple, all you need to do is create a scene, whether it be in front of your movie, or stand alone.
Setup a dynamic text box and name it flashversion.
Now using actionsript, set variable on the frame:
var flashversion = getVersion()
What this does is find out what the build number of the player that the user is using is. Also Actionscript will tell you if you are using a Windows machine or a Mac system, whether that's helpful or not, I can't figure that out. Enjoy!
