Ok so I went out and got a windows 7 pro hp laptop just for ffxi because my Xbox 360 version will end next year.I went onto the official download site and saved the 4 files listed "FFXISETUP" "data 001" "data 002" " data 003" ,I can see all 4 files saved in my downloads folder as 4 different files.instructions on site says double click the "FFXISETUP" file to start the installation process,when I do that all it says is windows can't open this file and suggests I go on net to look for a program to open it or look for one already installed to laptop.the laptop is brand new and I am completely new to using one too so if anyone knows what I'm missing or what im doing wrong please let me know,thx.
