I now believe that in my case the problem of "Setup could not verify the
integrity of the file Update.inf. Make sure the Cryptographic service is
running on this computer." was not due to problems with the 'cryptographic
service' as appears to be often the case but was related to the 'inf' file
association.. I found the 'inf' association in the Registry at HKCR was
missing (no 'install' on the drop down menu when rt clicking an inf file).
After I reinstalled the 'inf' association in the Registry (xp_inf_assoc.zip
courtesy of Doug Knox) the problem was resolved.
It seems clear from the record (Google) that in the majority of cases the
problem lies with the 'cryptographic.service' but my experience suggests
problems with the Registry '.inf' association may result in a similar
problem when trying to load MS updates. This solution seems to fit the
observed facts in my case, that is if I replaced the current Registry with
an earlier version, the problem was solved i.e. the inf file association was
restored. What I don't understand is why the inf association was deleted in
the first place and whether there is something in my system that will
systematically remove that file association. Time will tell, but at least I
now think I understand better why I have/had the problem and how to address
it..
Thanks to all who tried to help.
