256986 Description of the Microsoft Windows Registry

SYMPTOMS

When you view a Web page that has Microsoft Windows Media Player embedded in it, Windows Media Player 6.4 is embedded instead of Windows Media Player 9 Series or Windows Media Player 10. This behavior occurs even when Windows Media Player 9 Series or Windows Media Player 10 is installed on your computer.

CAUSE

This behavior occurs because the Windows Media Player 6.4 ActiveX control, Msdxm.ocx, was reregistered. The control may be reregistered by some versions of the Microsoft Internet Explorer Administration Kit (IEAK), by other applications, or by manual reregistering.

RESOLUTION

Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve this behavior, reregister the Wmpdxm.dll file. To do this, follow these steps:
  1. At a command prompt, type one of the following commands:
    • %systemroot%\system32
    • c:\windows\system32
  2. At a command prompt, type the following command:

    regsvr32.exe wmpdxm.dll

  3. Start Registry Editor. Verify that the following registry key points to the correct path and file name for the (Default) value:

    HKEY_CLASSES_ROOT\CLSID\{22D6F312-B0F6-11D0-94AB-0080C74C7E95}\InprocServer32

    Typically, the registry key points to the following path and file name:

    C:\Windows\System32\Wmpdxm.dll

STATUS

This behavior is by design.
