You may also need to download the
WinRAR program which you can also get at this site. This program puts the files back together. Make sure you make a directory just for these files and when you save place them into this

After you download the program use bittorrent to completely download the full program from the file you saved. Once this is done it might not need to be pieced together but if it does use WinRAR for that.
