The software, either FiatECUScan (FES) or AlfaDiag, is simple. My personal preference is FES because the free version does everything I need.
The harder part is setting up he USB port and driver (not always needed) for it. Once you are talking to the car the rest is really easy.
If you were closer I would do it for you; it can be a real pain sometimes but like changing mechanical components, after doing it once the second time is so much easier. However, it can also go right first time with no special effort - I have seen both.
Once plugged into your car it may not connect. There are two probable and one rare possible reason.
1. The OBD connector in the car has surface corrosion. Just unplugging and re-connecting the cable a few times is enough to clean this and make a connection.
2. The windows "port" needs its driver upgraded to the one in the link I have shown above. When you plug the cable into your laptop and before connecting to the car you will get a new port under PORTS. It is that port that needs the new driver.
3. There is one recorded instance of a car having wires behind its OBD connector loose and not connected.
