Solution:

Per Engineering and Product management: “It was decided not to do the significant refactoring of the code to allow non admin to use the software. Since the software uses code that requires administrator level access, the UAC manifest that sets the "Requested Execution Level" to "Require Administrator" was added. This allowed the software to run on Windows Vista as an administrator. The Vlinx Serial Server Manager does not have a registry key that changes its requirement for administrator level access. The following Microsoft Knowledge Base articles are about changing the system-wide UAC configuration; however, disabling UAC is a security issue and can not be supported by B&B."
