    AutoUpdate to 9.1.0 results in run-time error 53 : File not found

    • Product: Voyager
    • Product Version: 9

    Problem Symptoms

    • AutoUpdate to 9.1.0 successful from Voyager 9.0.0.
    • AutoUpdate to 9.1.0 fails with "Run-time error 53: file not found" if clients AutoUpdated from pre-9.0.0 version


    Name of AutoUpdate executable changed for compatibility with Windows in Voyager 9.0.0.


    Update the name of AutoUpdate executable for client install.

    1. On PC, open folder {client install folder}/System
    2. Find VerUpdate.exe
    3. Right-click on VerUpdate.exe > Rename
    4. Name file VoyDownload.exe
    5. Save change.
    6. AutoUpdate clients.

    Additional Information

    • Name of executable changed due to security changes made by Microsoft in Windows 7 and Windows 8.
    • Will need to follow steps to implement this change only once - future AutoUpdate will then have correct filename to work with.
