Have a look here for a start:
command line - Firebird custom installation - Stack Overflow[
^]
It looks you are missing the comand line parameter /COMPONENTS="comma separated list of component names"
E.g. for full installation: /COMPONENTS="ServerComponent\SuperServerComponent,ServerComponent,DevAdminComponent,ClientComponent"
I hope it helps
[Edit]
To install in a specific directory you can use command line parameter
DIR
E.g:
Firebird-3.0.4.33054_0_Win32.exe /DIR="c:\Temp\FB"
Notes:
1.) After a conventional installation you will find the two documents
"C:\Program Files (x86)\Firebird\Firebird_3_0\doc\installation_scripted.txt"
"C:\Program Files (x86)\Firebird\Firebird_3_0\doc\installation_readme.txt"
Especally installation_scripted.txt contains helpfull information
2.) If you start
Firebird-3.0.4.33054_0_Win32.exe /?
the standard "ino setup" command line parameters will be shown.
