Norton Power Eraser Cancelling on it's own

Today, 09.24.14, I download Norton Power Eraser, install, and run. The program prompts a shutdown then reboots, scans boot sectors and then on it's own puts the word  Cancelling with a button to exit. The circle is still rotating showing activity. Hangs this way for an hour before I exit it. Tried it on 2 computers, both with windows 7. Picture attached. Please help.
