I Googled and found quite a few "Runtime Error 52: Bad file name or number" error messages that are related to Visual Basic and/or Word. Perhaps you are running a VB tool as part of your installation?



As far as I know, there is no "error 52 bad file or name" error message defined in SetupBuilder. But a screenshot can tell if it comes from the installer engine. IMO, it is not a SB error code.
