I think that my, Cleaners, Ad and Spy Removers, may be my problem. I had been running these programs before trying Win Update. As I posted, the Update Site didn't work right for me. I then downloaded the files from the catalogue site. These downloaded fine, but when I tried to install them I got the message that cryptographic wasn't running, and Win update File could not be found.
I went back to a Ghost CD I had made a few days ago. After that the downloaded files installed fine, and another visit to the Update Site, found, and installed other updates fine!
