installer in silent mode doesn't work
 

because our installer is for upgading our software. It requires the installer should run in silent mode.

I trid to those command lines
----------------------------------
SilentInstall silent

function .onInit
SetSilent silent
functionend
-----------------------
But it doesn't work. I have added two custom pages with 3 checkbox (default is checked)?
How can i do?

Check with IfSilent into custom page's show function, set the default values for all 3 check boxes and skip to custom page's leave function.
