There seems to be a bug in the installation of the new Adobe Flash Player 11 that leaves this ad-on (“Shockwave Flash Object”) disabled. The result is that when you need it for video content—you get the message to install Adobe Flash Player again, even if you know that you just installed it and it said successfully. After I enabled (“Shockwave Flash Object”) - Flash player works fine.
This what I did to enable (“Shockwave Flash Object”)
First go to http://get.adobe.com/flashplayer/ and install Adobe Flash Player for your computer.
Click to open Internet Explorer.
