Stephen, Have you solved this problem yet?
I alsohave the same problem and have also installed AccessHW VIs. These however don't work with a CVI runtime engine later than version 5.5.1 see http://digital.ni.com/public.nsf/3efedde4322fef19862567740067f3cc/8566c7f0fc169bf686256cd40076533a?OpenDocument
