Automatic Liveupdates not working in windows 7.

I have Norton Internet Security on two laptops. One Windows 7 and  one Windows 8.

 

The Windows 7 laptop doesn't seem to be getting auto updates. The virus definition seem to be getting out of date all the time. I then have to manually update to get the definitions up to date.

 

The Windows 8 laptop auto updates regularly even if laptop is being used so I'm assuming that's how it should be working on the win 7 laptop.

 

What can I do to get automatic updates working properly on Windows 7?
