There are a lot of ideas in this article:
One part points to the page that lets you check if Flash Player is enabled in IE:
What operating system, including version and service pack if installed?
What version of Internet Explorer?
Flash Player functions without an Internet connection.
When you go to Manage add-ons the default view displays 'Currently loaded add-ons'. It's possible Flash Player isn't loaded. Select to show 'All add-ons' to view a list of all add-ons installed on the system (whether loaded or not).
Thank you. And I find that the add-on is in the "run with out permission", Do you know how to get the permission for the shockware Flash Object? IE version is 11, Flash for IE version is 24.0.0
