SYMPTOMS

When you view the Internet Explorer 4.0 Components Download page, additional components that are installed on your computer may be displayed as not installed.

CAUSE

This behavior can occur when the program that installed the component is not an Internet Explorer 4.0 Active Setup-aware program.

RESOLUTION

To resolve this issue, reinstall the component from the Internet Explorer 4.0 Components Download page. After you reinstall the component from the Internet Explorer 4.0 Components Download page, you are notified of future updates to the component.

MORE INFORMATION

The additional components available on the Internet Explorer 4.0 Components Download page are installed by default into folders in the Program Files folder on the drive on which Windows is installed, except for the Microsoft Interactive Music Control with Microsoft Synthesizer, which is installed in the root folder on the drive on which Windows is installed.

An Internet Explorer 4.0 Active Setup-aware program writes information to the following registry key:

HKEY_LOCAL_MACHINE\software\microsoft\active setup\installed components

When you connect to the Internet Explorer 4.0 Components Download page, this registry key is read to determine which components are installed on your computer. If a component that is installed on your computer is displayed on the Internet Explorer 4.0 Components Download page as not installed, the program that installed the component did not write to this registry key or the registry key has been removed.
