    MsiExec.exe /uninstall {37477865-A3F1-4772-AD43-AAFC6BCFF99F} /passive

Known issues with this update

  • Update 941833 for MSXML 4.0, for MSXML 4.0 SP1, and for MSXML 4.0 SP2 does not support the complete removal of MSXML 4.0. This situation occurs because this version of MSXML is installed in side-by-side mode. To work around this issue, follow these steps:
    1. Remove update 941833 by using the View installed Updates item in under Programs and Features in Control Panel.
    2. Delete the Msxml4.dll file from the %SystemRoot%\System32 folder.
    3. Repair the previous installation of MSXML 4.0 by using the View installed Updates item in under Programs and Features in the Control Panel.
    The earlier versions of the Msxml4.dll file and of the Msxml4r.dll file are restored to the side-by-side folder and to the %SystemRoot%\System32 folder.

    Note The HP printing software sometimes locks the Msxml4.dll file regardless of which operating system you are using. Therefore, this file may not be deleted. If this file is not deleted, you must restart your operating system and then delete this file in safe mode.
  • You may receive the following error message when you install update 941833 from Windows Update:
    Could not register type library for file c:\Windows\system32\msxml4.dll. Contact your support personnel.
    When this issue occurs, you may also notice information that resembles the following in the log file:
