Problem scenario
You got an error message about needing Norton Power Eraser (and that a common reason for installation failure of Norton is an infected computer). You clicked on the link and got a message about a boot recovery application with an .iso file. What should you do as it does not seem to match?
Solution
Ignore the link in the Norton app. To get Norton Power Eraser, you can go to Norton's site.
Once you have the application open on your desktop, you may want to go to "Settings" to include the Rootkit scan before you start the scanning process.
