Cannot install Windows Media Player 11 plugin. Not even manually
Since I can't install the Windows Media Player 11 plugin through the plugins section, I tried installing it manually from the link http://port25.technet.com/pages/windows-media-player-firefox-plugin-download.aspx multiple times and it still will not show up in aboutlugins. I followed instructions from Firefox and rebooted after the install and still won't show up. I am using Windows 7 64 bit and have the latest version of Firefox. cannot play videos embedded in websites that support windows media streaming.
After installing, I reopened FF but the plugin was not listed. I tried the "Install Add-on from File" option, navigated to the DLL, and it said it could not install the plug-in because it "appears to be corrupt."
I tried a couple more times because one thread said it worked after getting the installation package from a different mirror, but no luck.
