How to Call Install button Click Event automatically???

i have made a setup package with one screen/Page. as i click on Setup.exe it shows me a dialog box with blue background . on the bottom of the dialog box i have two buttons named Cancel and Install. Install is the default.


can anyone tell me how can i call the click event as user Double click on my setup.exe.

So you want it to go straight to the installation without the user having to click Install?
Just insert the InstFiles page with no other pages.

thanks for suggesstion. my setup works fine, it requires restart/reboot system. i have added a new key in System's registry in RunOne. so my setup.exe starts automatically. now i want to click my Install button automatically.
