I really don't think you can do what you want to. You can easily enough copy data from one PC to another, but each program you have installed on your old PC will need to be reinstalled on your new PC, using either the original software disks or redownloading the software from the web.
That said... I just looked at the zinstall site - I'd never heard of zinstall before - and if they can really do that, it's very impressive. It doesn't look cheap, though. I'd check online for some reviews first.
