Maybe your are experiencing this like me: Your IE7 do not show flash content from some websites, even with Flash Player 9 installed on your system, and everything working fine with IE6 or Firefox.
The fact is for some reasons IE7 corrupt Flash Plugin, in result flash detection on websites do not work. And if you try to click on one of the "upgrade Flash plugin" button the browser consider it is already installed.
Here is a solution:
If this do not work you can also try :
- Download the Flash Player standalone installer for Internet Explorer
- Then right-click on the installer and choose "Run as Administrator".
