Seems like either the installation file is corrupted, or you dont have enough space to install. Try redownloading the file from
[Only registered and activated users can see links. Click Here To Register...], (or a less easy way, but it'll save you hours of downloading: grab the torrent from
[Only registered and activated users can see links. Click Here To Register...] and open it up in utorrent -
[Only registered and activated users can see links. Click Here To Register...]. Start downloading the file, but then stop it after a few kilobytes. Replace the file that you are downloading
WITH UTORRENT with the file you
ALREADY DOWNLOADED. Go back to utorrent, right-click the torrent and select Force Re-Check: this will recheck the file for any errors. Once that's done, you can resume the torrent. You will only need to download a few megabytes that was corrupted.)
