When I did this about half an hour ago I got:
1) Right click "run as administrator":
2) Security Box appeared:
3) Clicked "Yes":
4) Waited a little while and the Blue/White box appeared automatically without me doing anything:
5) Selected "Update Now" and updates installed OK.
Try waiting after step 3 to see whether the upgrade box appears without user intervention.
If above doesn't work, try adjusting your preferences for the program to automatically launch at Windows Startup and also perform regular automatic updates.
