Adobe Reader XI plug-ins for IE8

I am updated to Adobe Reader XI 11.0.02 according to "Help/About Adobe Reader XI," and my "Add or Remove programs" on XP- SP3 says 11.0.02.  Also, my plug-in for Chrome says 11.0.02. But, my IE8 plug-ins still say 11.0.01.36 for Adobe PDF Reader and 11.0.0.379 for Adobe PDF Link Helper.  I uninstalled reader and reinstalled and still the same thing.  Why won't the IE8 Reader plug-ins update? 

Thanks.
