If this is just happening, it may be a new upgrade thing. As of this past Sat we can't get Adobe Flash on our computer either. Ours is a new computer with 64 bit &something was changed & Adobe is no longer available on 64 bit computers, at least not for now. I was playing my games Fri night & Sat I couldn't do anything. Now we have to go into Internet Explorer 64 bit & everything is messed up. I'm always getting that notice to install it too but it doesn't work anymore.
