After upgrading Equitrac to version 6.2 Fixpack 3, the following message is displayed in the event viewer, and print jobs are no longer able to be submitted to Equitrac via the Windows Print Spooler.

Under the Print Service Admin log, the following entry can be found if the Admin Logging is enabled

Log Name:      Microsoft-Windows-PrintService/Admin
Source:        Microsoft-Windows-PrintService
Date:          <datetime>
Event ID:      808
Task Category: Initializing
Level:         Error

The print spooler failed to load a plug-in module C:\Program Files\Nuance\Equitrac\Port Monitor Hook\NDI.LanguageMonitor.dll, error code 0x7E. See the event user data for context information.


This is caused by the registry key for the NDI.LanguageMonitor.dll pointing to the previous Nuance directory. As of ControlSuite 1.2 this has been moved to the Kofax Directory, however during the upgrade the registry keys was not updated.

Note: The below steps involve editing the Windows Registry. It is strongly recommended that a backup of the registry and the server has been performed before performing this procedure

Enter How to here:

  1. Stop the Windows Print Spooler Service

  2. Validate the location of the NDI.LanguageMonitor.dll file on the Hard Drive. The default location is C:\Program Files\Kofax\Equitrac\Port Monitor Hook\NDI.LanguageMonitor.dll

  3. Launch the Windows Registry Editor (RegEdit)

  4. Using the Find function, search for "NDI.LanguageMonitor.dll"

    There should be several entries under the ControlSet items. This may vary based off of Operating System.
    For example, they have been found under the following Registry Locations
    HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Print\Monitors\ NDI Language Monitor
    HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\Print\Monitors\ NDI Language Monitor
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors\ NDI Language Monitor

  5. Locate the REG_SZ entry for Driver and update the path from \Program Files\Nuance to \Program Files\Kofax
  6.  Repeat steps 4 and 5 until all the entries that contain the NDI.LanguageMonitor.dll have been updated.
  7. Restart the Print Spooler.
