My only thought is that there is an issue with access rights. So far the executable works correctly on an older server (Windows Server 2003), the development computer (Win XP), and my company laptop (Win7), but the executable does not archive the data on the Server 2012 server or on another computer running WIndows 7. I have all of these machines logged in as the same domain administrator account, but IT networks are admittedly over my head, so I wanted to check here to see if anyone has seen this issue with WinRAR and/or the System Exec.vi.
