Ground Controls->Non_PDF->File->Application


Application - This Ground Control will trigger if you have scanned a document created with an application that is not present on your system. 


Unreadable, Unsupported, or Locked - This is a catch all Ground Control basically it triggers if  the document you are scanning is a file format that FlightCheck does not understand, or the document is locked because it is in use by another application. **Note - This error is most commonly seen when a supported file format is scanned but the file contains some data that FlightCheck cannot understand. FlightCheck aborts the preflight gracefully by displaying this message. If you see this message, you should fill out  our Tech Support Request Form and send us the file. If you do not send us the file, we have no hope of discovering what FlightCheck cannot understand in the document.
