Let's say I have a form with a button on it. When I press the button, a messagebox pops up saying 'Hi.' Now let's say a user has this application installed on their computer via the installation project. My question is, how can I create an 'updated' app to overwrite information on the app they already have (for instance, from v1 to v1.2)? For practice purposes, the updated app would make the messagebox show 'Wow!' instead of 'Hi.' Thanks.
