>If I use the Setup Wizard to create a setup disk, first time setup works OK.
>
>But when I update the program and try to run from the the new setup disk, I get an error message suggesting that some file may be damaged, and that I should try to run setup from the same location as the original setup. I try over and over again, but with the same result.
