If a project has already been installed, is there a way to notify the user that it is already installed and give them the option of overwriting or canceling?
Also, is there a way to install an upgrade without losing the data in the previous version?

If your app has a Registry entry, just perform a RegistryRead. Otherwise you have to look for a known directory or perform a drive search; eventually with user interaction.
What “data” you want to keep is totally up to you.
Both questions can be answered with “YES”. SUF70 obeys your orders.
