InstallAware

Hello i'm trying to create a silent install, but i saw that using '/s' the RunNow function is no longer working (kind of normal, huh?) But still i need to do a silent install with the RunNow option still working.
I have to mention that i removed all the other dialogs except two basic dialogs:
1) "InstallAware is verifying the contents of this setup package..."
2) "InstallAware is prepering to install... "
- how can i remove these two and RunNow still working ?
Thx

if Variable SILENT Equals FALSE
-- i missed this, so if i run the setup with '/s' and remove also that condition, RunNow works fine!
