I am operating Windows Home (64 bit). I use NORTON Security software. When I open a website that requires Adobe Flash Player 11, I try to download the required file. After going thru the steps to downloade the Flash Player 11, I get a screen that says I have sucessfully downloaded Adobe Flashplayer 11. However every time I try to use a website that requires Adobe Flash Player 11, it says that I don't have Adobe Flash Player 11 installed & that I need to down load the file again. I have done this about a dozen times. What am I missing????
