Norton 360 v21 does not work in Windows 8.1

Hello:

Norton 360 v21, in the cloud there is no way to work, I have Windows 8.1, I've tried everything, installing, reinstalling, and mail account and can not access the passwords I had in another computer with Windows XP.

I think Norton 360 is incompatible with some protections in Windows 8.1

I pray immediate solution

thanks
