You may get the following error message:
A modal dialog box is showing in the QuickBooks user interface. Your application cannot access QuickBooks until the user dismisses the dialog box.
The error occurs when a modal window is open in QuickBooks. This modal window requires users to close it before returning control to the application. Until such modal window is closed, you cannot click anywhere else than on that particular window and ReconPro QuickBooks Exporter doesn’t have access to QuickBooks as well.
To fix the issue, close modal window.
Examples of modal windows:
Internet Security Levels Were Not Set Correctly warning
QuickBooks Update Service
