Setup error messages
The setup.exe executable file might produce error messages if it cannot start properly.
In most cases, you will encounter these messages when a severe error occurs. Your users will rarely see these messages. Every error message has a unique number. There is no way to suppress error messages in your script.
If you encounter an error, you can go to the Knowledge Base, InstallShield support
website at URL: http://support.installshield.com/default.asp,
and search for information about the specific error.
