Subject How to make my own installer install firebird with my application in

I want to create my own installation to install firebird with my application.
i have downloaded the manual script and i need to attach my own security2.fdb as my own userid/password is saved with this db.I have replaced my system security2.fdb in the firebird folder where the downloaded security2.fdb is located but when i run install_classic.bat it runs successfuly but when i connect from flamerobin with my shipped db it gives an error msg and i have checked firebird service is running.

i dont know whats wrong i m doing.Please, help in this regard I am struck to give an installation module to my end user.
