Norton toolbar 2011 and IE 64 bit

I am running both IE 64 bit and IE 32 bit with Windows 7 on my laptop.  In IE 32bit the Norton Search bar, Safe Web and Identity Safe were added with ease.  I thought I would start using IE 64 bit but the Norton toolbars are not added and when I go to Manage Add-ons, I can't seem to add the toolbars.  How can this problem be solved?  I have search Symantec's support to no avail.
