Reinstalling Norton 360 and need key help
I have one copy of Norton 360 that will expire in about 30 days and is in use on 3 computers. I recently purchased another copy of Norton 360 to use on a fourth computer.
I would like to purchase a third copy of Norton 360 to replace the version that will expire in about 30 days rather than paying the price to renew from Symantec. There is a difference in price of about $20.
What are the exact steps to use the key from a third version of 360 that I will purchase to replace the copy that will expire in about 30 days and is being used on 3 computers? I do not want to have to uninstall and reinstall the existing software on the three computers that are using the copy that is about to expire.
Thanks for any comments.
