I'm trying to get an unattended CD going, but I can't get Delphi7 installing silently... when I use the silent switch (/qn) it starts, then says "The serial number or authorization key is invalid. Installation cannot contine." Does anyone know how I can tell it my serial number, authorization key, and if possible, what options to install? e.g. It would be great if C:\delphi7.msi /qn /SERIAL:XXXX /AuthorizationCode:XXXX /Installdir:XXXX obviously the above doesn't does anyone know of a solution to this?
