This article was previously published under Q300188

SYMPTOMS

If MSXML 3.0 is installed in replace mode and the dynamic-link library (DLL) is unregistered, all registry entries for previous versions are removed, and Web applications that were using MSXML no longer work correctly.

RESOLUTION

Reinstall the previous version of MSXML to restore the component.

STATUS

This behavior is by design.

MORE INFORMATION

Steps to Reproduce Behavior

  1. Install MSXML 3.0. During setup, select Replace Mode.
  2. Unregister Msxml3.dll. Applications that use MSXML no longer work correctly.
