Has NIS 2011 Upgrade To 18.6.0.29 Worked OK?

Running Windows XP Home, Service Pack 3, Fully updated
Internet Explorer 8
Norton Internet Security 2011

 

LiveUpdate has upgraded my NIS 2011 to Version 18.6.0.29 as shown by Support/About

 

However there are still the following directories referring to Version 18.5.0.125  :-

 

C:\Program Files\Norton Internet Security\Branding\18.5.0.125
C:\Documents and Settings\All Users\Application Data\Norton\{0C55C096-0F1D-4F28-AAA2-85EF591126E7}\NIS_18.5.0.125
C:\Documents and Settings\All Users\Documents\Norton\{NIS_prod_1.6.18_18.5.0.125}

 

Is this correct or has there been a problem with the upgrade?
