Falcon,
Downloading drivers to a cd will work if you know what version of the drivers you need. The video drivers are specific to the video card and not specific to the cpu. If you do not have a Video card that meets FSOne's specifications that that will be a reason it will never work.
So, maybe the first step is does your hardware meet the minimum requirements set forth by FSOne? This is critical. Go to the Horizon Web Site and see what the requirements are, or just check the box.
Get one of the free antivirus programs and connect to the internet. Get the Drivers you need and let FSOne help you.

As I see it, there is not magic fix for you. The problems you are having are either inadequate hardware, or drivers that are too old.

You also need to connect to the internet to get the updates for FSOne.
