Hi, If you do want to uninstall the old executable, then you want to make sure that you are NOT generating a new product code every time you ubild a new executable. When you are in the Application Builder >> Installer Settings >> Properties, make sure that you are keeing the same product code (do not press the product code Generate button). The old executable should now uninstall first before installing the new executable.
