I am running Windows 7 ultimate with service pack 1. I have duel intel 1.6ghz processors, 2gb ram, 64 bit OS and all my windows programs are updated to date. I have most recent flash player installed, yet when I use IE to watch videos it doesn't recognize it and tells me I need to install it, yet when I try to install it I am told only one single instance of the application can be run at a time. When I use chrome video plays fine! I have been following posts and advice of Pat Willener and nothing seems to help. I have also noticed that I am not the only one who experiences this same issue.
