When you try to reconnect the company file to a third-party application or to Warehouse Manager using the QuickBooks Web Connector, you see this message:

Error QBWC1039: There was a problem adding the application. Check the QBWCLog.txt for details.

followed by:

Error Unique file ID required.

This error could be caused either of 2 things:

  • The company file has been moved from its original location.
  • The third-party application or Warehouse Manager was incorrectly removed from the QuickBooks Web Connector.

Reinstall the .qwc file to Web Connector

  1. Download the QBWC CP3Tool. (Note: This download requires Internet Explorer 10, Chrome, or Firefox browsers.)
  2. Double-click the QBWC_CP3Tool_Installer.exe file to install the tool.
  3. After the installation completes, select Launch the QBWC CP3Tool.
  4. Minimize the tool.
  5. If you haven't done so already, download the .qwc file for your application:
    • If you are unsure how to get the .qwc file for another application, contact your third-party vendor for more information.
  6. Open QuickBooks Desktop and select the company file you are having trouble with.
  7. Make a backup copy of this company file. (The tool asks you to do this, so it is easier to do it first.)
  8. Bring the QBWC CP3Tool back up on the screen by clicking it in the Taskbar.
  9. Click Select File and locate the .qwc file.
  10. Click Remove Stamp.
  11. When the Application Certificate appears, select the third option, Yes, whenever this QuickBooks company file is open, and then click Continue.
  12. In the Application Access Request window click Yes.
  13. On the access confirmation message, click Done.
  14. Click OK on the message asking you to make a backup, since you already did this in step 7.
  15. The QBWC CP3Tool displays a confirmation message if the owner ID was successfully removed.
  16. Close the QBWC CP3Tool.
  17. Install the .qwc file to the Web Connector:
    1. Open Web Connector and click Add Application.
    2. Go to the .qwc file for your third-party application and open it.
    3. Enter your third-party password in the Web Connector, and click Yes on the message to save the password.
The Web Connector is now ready to sync.
