From the version number you have provided, you have an old version of NIS installed. The most current version (NIS 2012) is 19.1.1.3. I do not believe however that anyone will be willing to guarantee that you will avoid this problem in the future. Chances are very good you will, but no guarantee.
I will receive some flack from suggesting this method, as most folks still do not trust or use the Norton Remove and Reinstall Tool, however I would like for you to try it and if it doesn't provide you with an error free install, we'll let one of the Guru's supply you with the old method. So if you are game, try this.
If you use Identity Safe, backup your Identity Safe data: (The NR&R Tool does this as part of it's function, however, due to the critical nature of the information contained in ID safe we would recommend backing that up manually first just as a precaution even though the tool should do this for you.)
Follow the instructions for downloading and running the Norton Remove and Reinstall Tool
Be sure to read the Before You Begin in the above link.
After the program is installed and activated, manually Run LiveUpdate as many times as necessary for it to respond "no more updates available". If a reboot is requested, reboot and then continue to Run LiveUpdate until it responds "no more updates available" and then reboot one last time.
If you decide not to try this method, please post back and ask for the old method.
These are the instructions PaupauZ normally posts:
1. If you use the feature, please backup your Identity Safe data 2. Download latest Norton Internet Security installer: www.norton.com/nis12 (this is the English one, for other languages please go to the Norton Update Center: www.norton.com/nuc ) 3.
