Since it's been a trial for some to find, I've provided the client download link above for future use, if not an example of how easy you 'can' find it if your Google search terms r straight forward and to the point (I just searched 'FFXIV download' and found it at the very top of my suggestion links).
On a side note, one can even troubleshoot and fix their own computer without taking it to a shop and dishing out cash, but again, that depends on the individuals 'capacity'..
