hi,
if u want to use a windows installer then you can use installer as this

Firebird-2.0.0.11675-0-Win32.exe
/DIR="%SystemDrive%\NitiSoft\FireBird" /Silent

for only hiding of next sequence or

Firebird-2.0.0.11675-0-Win32.exe
/DIR="%SystemDrive%\NitiSoft\FireBird" /verysilent

for hiding all dialogs
