Norton Ghost 15 with Quantum LTO-5 internal tape drive

Purchased Norton Ghost 15 to backup to Quantum LTO-5 internal tape drive.  Running Windows 7 Ultimate 32-bit.  Windows lists the tape drive in device manager under Tape Drives, no conflicts, device ok.  However, Ghost doesn't list the tape drive as a selectable backup destination.  I bought ghost because in another forum answer it was stated ghost works with tape drives, so I'm wondering if I have a setup issue or if tape drives are no longer supported?
