QuickBooks Desktop: Error Code: 80040414

Issue:

• Error Code: 80040414. A modal dialog box is showing in the QuickBooks user interface.
  Your application cannot access QuickBooks until the user dismisses the dialog box.

Cause:

If dialog boxes are open in QuickBooks (notifications, information page, etc), it will freeze the company file until the dialog box is dismissed. After the dialog box dismissed, the integration application may access the QuickBooks company file

Resolution:

1. View open QuickBooks company file
2. Close any open dialog boxes
3. Re-run integration application
