No effect after deploy .ins problem ( IEAK7)

A package of IE7 is created by using Customization Wizard of IEAK 7 with
some customized security settings.
This package is installed on few computers and can apply those customized
settings successfully. I also
use IEAK Profile Manager to create update.ins and update_config.cab by edit
the original .ins file
of the package. However when I double the update.ins, it prompt "Warning you
are about to change
your Internet settings..." but no effect after I click OK.
I tried to re-pack for few times and sure "Automatically detect
configuration settings" is enabled.
Also tried to "Enable Automatic Configuration" and put the update.inf and
update_config.cab to web server
but still not effect.
