I have a working setup and i want to get rid maintenace dialog box, what happening is when i run the setup for the first time it goes smooth. But if i want to run the same setup again, its coming up with a dialog box(Modify, Repair, Remove) , so i dont want see this box any more, how can i do that. And one more thing when setup runs it adds a registry key depends on that i detects that it installed before, where can i find that key and how can a setup without adding that registry key.
thanks
