Event Type: Error Event
Source: SideBySide
Event Category: None
Event ID: 36
Date: 12/30/2003
Time: 10:06:07 AM

Description: The assembly x86_Microsoft.Windows.Common-Controls_6595b64144ccf1df_6.0.2600.1325_x-ww_7abe6cc7 has missing or invalid files; recovery of this assembly failed.

You may also receive the following "Windows File Protection" error message:
Windows File Protection
Files that are required for Windows to run properly have been replaced by an unrecognized version. To maintain system stability, windows must restore the original version of these files.
This problem occurs because the side-by-side component does not correctly delay the Windows File Protection process when an in-place update of the side-by-side assembly occurs.
