You do need to add tile Package Kreator as a registered app on your portal. The steps are the same as are described for Survey123 here How To: Add Survey123 for ArcGIS as a registered application to Portal for ArcGIS 10.3.1. The difference is the app id and that you would need to do it for any version of portal (Survey123 is automatically available for portals 1.4 and newer).
