SYMPTOMS

When you install an MSDN Library 2002 edition without errors, and then you try to run the Help Viewer, you may receive the following error message:
The application cannot start.

CAUSE

This behavior occurs if the MSDN Library Help Viewer cannot load Msxml3.dll. The beta release of the MSXML 4.0 Technology Preview, which is obtained through the July 2001 Security update, incorrectly changes the registry. You cannot undo the registry changes by removing the MSXML 4.0 Technology Preview.

    1. Click Start, and then click Run.
    2. At a command prompt, type the following:

      regsvr32 /u Windows Directory\system32\msxml4.dll

    3. Click OK.
