You can buy WIS/ASRA/EPC on ebay. It's sold as 4 DUAL-LAYER DVDs, so make sure your DVD reader can read dual-layer, if it can't, regular DVD players will only read the first layer, making it seem like it works but copying the files will always stop at 50%! It's also pretty cheap!
You do need to have vmware player installed for the program to work, if you are interested why, read the next paragraph, if you don't care about computer science, just install it and don't question my judgement. vmware player is free, unlike it's professional counterpart vmware workstation, and is very excellent software! (Imagine it this way, vmware is to computer science what lemforder is to mercedes, a company that you can trust).
Now the computer science bit. You need to have some virtualization software installed on your computer to run virtual machines. Imagine if the computer's hardware and software were totally abstracted from one to another. Instead of the software having to worry about what's going on with the hardware, the hardware is merely allocated as a resource to the software, with the rest going on under the hood. This allows one physical computer to be running multiple virtual computers. This is actually an extremely efficient way of allocating computer resources. Think of it this way: imagine you have a bunch of physical machines that don't do much work because they have little load coming from users/services. Instead of wasting all this electricity running physical machines, you can create virtual machines, and run all of them on one computer, fully utilizing that computer's hardware. This is clearly more efficient, and it frees up your other physical machines to be doing the same thing! So you could have 1 physical computer running 10 virtual ones (more powerful computers could run even more than that). There is a good side-effect to this practice, it makes entire virtual machines easy to move from one physical computer to the next! You only need to copy/paste the data, and you don't have to worry at all about reinstalling the operating system and all the drivers and reconfiguring everything. In our case, this allows full installations of WIS/ASRA/EPC to simply be copied and given to other users. I won't get into serious details about exactly why WIS/ASRA/EPC needs to be installed this way, but just trust me when I say it is needed for some parts of the full star diagnostics system, technically EPC and WIS and ASRA can be installed independently of the operating system (since they are made in Java, which itself runs on its own virtual machine), but it is much simpler to have users install vmware and receive a preconfigured virtual machine.
So how deep does the rabbit hole go? Virtualization doesn't require a host operating system. So you don't need to have windows installed to run virtual machines, you can install a program called vmware ESXi directly on your machine's hardware, and start deploying virtual machines directly. A host-less system, cool stuff.
You may be wondering how widespread this practice is. Well that's simple, it's the only practice. Every online service, website, server etc. you've accessed in the past 10 years hasn't been directly running on hardware, everything is virtualized today. If you've ever heard of the term "cloud", it's nothing special, or magical, it's just virtualization, the most efficient way to use a computer.
