Bad Filename or Number Error 52 exporting TIF files to a network location


Question / Problem: 

Exporting .TIF files to a network location from a Scanning Application using Kofax VRS results in the following error:

-52 Bad File Name or Number

Answer / Solution: 

A recent Windows 10 update, "Update for Windows Defender antimalware platform", causes Windows Defender to block Kofax VRS / ImageControls from saving the scanned pages to network locations.

Add the following paths to the Windows Defender Security Center Exclusions list on the target image storage location Server and each Kofax VRS scan station:

  • C:\Program Files (x86)\Kofax\
  • C:\ProgramData\Kofax\
  • The parent directory of the target export location
  • Any folders related to the scanning application (as recommended by the manufacturer of the scanning application)
  • Add an exclusion to the Windows Defender Security Center Exclusions list for the .TIF file extension on the Capture Server and each Capture Workstation

Kofax is actively investigating this issue with Microsoft to determine root cause and prevent this issue in the future.
