Good! I reinstalled Qlik Sense Desktop and when I go to the control center there is no app. The developed app is in "C: \ Users \ {user} \ Documents \ Qlik \ Sense \ Apps". I installed it again but the same thing happens. Also when I want to create an app I get the msj that is shown in the image. It lets me drag app (.qvf) to the control center and opens them without problem. Thank you! regards
