After publishing the project in Adobe captivate 19, am getting this pop-up warning.

Reason 1: You have SCORM reporting turned on in Quiz Settings but you are trying to play your content without having uploaded it to an LMS.

Reason 2: You have NOT set up SCORM Reporting in Quiz Settings but you have uploaded your content to an LMS and it cannot communicate with your content.

Reason 1 is the most common.
