Hi @MekAn! As you are new to the community, when you get a chance, please introduce yourself here .
Can you tell us a little more about the problems you are having? Specifically, have you installed Survey, Tables, and Services as well as OI file manager? Which versions are you using?
Have you tried opening the apps exactly as downloaded (so with the default forms)? Did that work (if the default ones worked then the problem is likely to be specific to your survey/tables)?. Can you share your forms?
