Version update after re-imaging

Hello -  I have used a full-system disk image to restore the computer but the NIS  version is stuck on the one that was current at the time the image was made, this being version 19.2.0.10. I note that the latest should be 19.6.1.

 

I have tried running Live Update a number of times, some of these attempts being after rebooting the computer. However, no joy with updating so far. Will this resolve itself if I keep on trying, or will a reinstalling of NIS be necessary?

 

Edit: Sorry - should have added that I'm running Windows 7 Home Premium 64-bit,
