Open QuickBooks Desktop
Download the QBWC CP3 tool
Download the QBWC CP3 tool, which Intuit (the makers of QuickBooks Desktop) created to fix this issue. Then open the program (“QBWC_CP3Tool.exe”) from your downloads folder.
Select the QWC file
In the window that opens, as shown below, click “Select File”, find the QWC file that you tried opening earlier that gave you the error shown above, and click “Open”. This file is often found in your downloads folder.
Click "Remove Stamp"
Grant permission to the CP3 tool
QuickBooks Desktop will prompt you to grant permission to the CP3Tool so that it can make a change to fix the issue:
In the QuickBooks Application Certificate window that appears, click “Yes”, then “Continue”.
On the Access Confirmation window, select “Done”.
Follow the instructions, then select “OK”.
Exit the CP3 tool
You should get a confirmation that the Owner ID was removed. Select “OK” and then close the CP3 tool.
Add the connection again
Attempt again to open the same QWC file you tried opening earlier. This time, it should work without any errors and you should see the connection added to the QuickBooks Web Connector.
