Depends from setup.

I have 1 more question, some setup need key during installation process,( like nero, office) Is these any way to add key yo the setup file and the setup can install silently?

First way, search in www for silent switch ( http://board.vitaligraf.de/showthread.php?tid=158 ).
Second way search www for autoIt-script for your app ( http://www.msfn.org/board/index.php?showforum=101 )
or create it self ( http://www.autoitscript.com/autoit3/ )
