Installshield, how to verify internet connection before installation?

I am using Installshield for the installation of a product.

I am attempting to find a way to verify an active internet connection before I continue with the installation of my product.

I checked all over, even the manual/help guides from the Installshield people.

I am setting "Program Features" through the Installation Designer->Setup Design->Program Feature(s), and figure if anyplace, it would be in here.

Has anyone worked on this before, and found a viable solution?

ps: I am also trying to find a way to check for minimum system requirements as well (NOT THE O.S. Version, just simple things such as minimum physical memory and minimum RAM)

It's possible, but I wouldn't do it in an install, I would do it in the application as the state of the internet connection could change after the install is performed.

I'd also want to clearly understand why this is required before implementing it. For example I have no direct internet access ( by design ) where I do my software development for security purposes. If I couldn't install or run software because of that, I simply wouldn't buy the software.

Then there are security implications of software applications and installs phoning home and hence why I stay disconnected from the internet on certain machines.

That said, to test for an internet connection, you first have to define what that means. Perhaps you have a public web service that you want to invoke?
