Why won't the newest version of Adobe Flash Player install on my Firefox?
I am trying to install the newest version of Adobe Flashplayer onto my Firefox (the Adobe version is 220.127.116.11) but it will not let me. It allows me to download the installer, and then it installs until about 45% and then says "Please close the following programs to continue" and it says Firefox is the only one open. I have closed Firefox and made absolutely sure it's not running, but it still says that it is running and refuses to install. Is there something I am doing wrong? The Firefox version is 11.0 and I use Windows 7.
