My IE 10 broswer doesn't recognize that I've updated to Flash Plyer version 11? It continues to tell me I don't have it - even when I can see it is on my program files (?)
You CAN'T see it in your program files because it ISN'T a program - it's a browser plugin, and in the case of IE 10 for Win 8, it's updated through Windows Update. Additionally you may need to re-enable it after the update.
