Immediately following my installation of Catalyst - Flash stopped working in Internet Explorer 7. My company website uses flash and its my home page - so I am sure that the Catalyst install was when it stopped working. I get a notice that Flash is needed for the website, I choose to install it and I get this error message: "Failed to install. For troubleshooting tips, please see http://www.adobe.com/go/tn_19166." I have followed their instructions from that webpage several times. In addition, I have uninstalled IE7, reinstalled IE7 and just installed IE8. And still get the same error.
Flash is working properly in all other browsers...Firefox, Opera, Chrome
That's a serious bummer. You should uninstall and reinstall the Flash Player.
Here's the article on how to uninstall:
When you reinstall the player, you should install the version that's included with the Catalyst installer. You can find it in CATALYST_HOME/player/win
Let me know if it works.
