Windows 7 / Getting Started

An Add-on Does Not Work Properly

Occasionally, a Web page might require you to have a specific add-on. If the Web page displays a message indicating that you need to install the add-on, you should consider the security risks carefully before installing it.

If the page continues to display improperly after you install the add-on, the add-on might be disabled. Users can disable add-ons manually, or Internet Explorer might disable a problematic add-on automatically. To enable an add-on, follow these steps:

  1. In your browser, open the Tools menu, select Manage Add-ons, and then click Enable Or Disable Add-ons.
  2. Click the Show list and then click Add-ons That Have Been Used By Internet Explorer.
  3. Select the add-on that you need to enable and then click Enable.
  4. Click OK.

If the add-on later becomes disabled again, Internet Explorer probably disabled it because it is crashing. Visit the add-on developer's Web site and download the latest version-an update might be available that solves the problem. If no update is available or the problem persists, you can disable the ability of Internet Explorer to disable the plug-in automatically. To disable Crash Detection, enable the Turn Off Crash Detection Group Policy setting in either Computer Configuration\Administrative Templates\Windows Components\Internet Explorer\ or User Configuration\Administrative Templates\Windows Components\Internet Explorer\. If the problem occurs on a single computer, edit the setting in local Group Policy. If the problem occurs on all computers in a domain, edit the domain Group Policy settings.
