Questionnaire definition (.mdd) files opened directly from IPlayerConsole.exe must contain system variables. If system variables are not present, attempting to open the file results in the following error:

Unable to create interview: The metadata system variables must be enabled

To avoid this error, open the questionnaire through the UNICOM Intelligence Interviewer interface, or contact your administrator. For more information, see UNICOM Intelligence Interviewer for UNICOM Intelligence Data Entry interface.
