I'm trying to create an updater that will install an application only if a previous version of the application exists on the user's machine. However, it seems that if a previous version does not exist (and so the install fails as a result), the user can still go into the contents of the .pkg and unarchive the Archive.pax.gz, and get the application even if they do not have a previous version of the application on their computer. Is there a way to prevent this? This email sent to site_archiver@lists.apple.com
