I just reinstalled Windows NT onto a computer and now when I try to install Norton's Antiviris I get an error message Symantec Error. "Set up has found an incomplete installation. Please reboot and reinstall"

Whenever I restart and try to reinstall I get the same error. I think that maybe there are a few stragling files left in the registry.

If any knows where in the registry norton places all it's files please let me know.
