Deploy the original application; don't deploy a published ClickOnce
wrapper. Those are intended only for apps that don't have an installer.
Also: never assume that you can save settings or data in the app's
folder. If you are prompting the user where to save files then default
to saving them in their Documents folder; if you are saving files
automatically then default to an app-specific subfolder of their
AppData\Roaming folder.
You can use Environment.GetFolderPath to get the full paths to these
folders.
