When a video comes up on a news site, it says flash player not installed. I checked and the site says it is installed and updated. I tried to uninstall and it tells me to close all windows. I did that and it still says close windows. I cleared cookies and history and rebooted and tried to uninstall and it still says to close all windows, which aren't open. I went to adobes site and tried to install from there and it tells me to close all windows. I downloaded the uninstaller to my computer and tried to run it and it says to close all windows, which are closed. Help!
