You can also go to the Norton Update Center to download and install the latest version of your Norton product for windows.
Norton product for Mac can be updated only from your Norton account.
I had Norton 360 Premium on my computer to protect against viruses and malware. I ran scans after re-starting, and Norton informed me that my computer was safe.
The last time this happened, I was unable to run a restore program, and could only get a blank screen.
If you are trying to download the Norton product from your service provider, go back to your service provider's website, and follow their instructions to get the latest version of your Norton product.
This all started yesterday when I tried to open my vault (NIS version 220.127.116.11 running on Windows 8.1 laptop) and it failed to open after I had entered my vault password.
I have also tried a couple suggestions I've read on here.
Additionally, the auto renew price is double what the same product costs retail. It is not the wireless service or modem, or the computer.
The other two I am reluctant to leave on for any length of time.
I've disabled fast start on all, tried a couple more fixes.
I had to physically remove the licence before I could do this as I had already used the 3 allowable licences and the Norton Removal Tool didn't remove the licence for me as part of the uninstall (why can't you make things work properly, Norton? And yes, before anyone asks, I used the Norton Removal Tool 3 times before reinstalling NIS.
Anyway, the same procedure as for my first attempt - running liveupdate a few times, applying the patches and then still finding that I get the "failed to complete" message.
