  <pre><code>WRN: Assembly binding logging is turned OFF.
  To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
  Note: There is some performance penalty associated with assembly bind failure logging.
  To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].
