What are you downloading? And from where? Please be careful of downloading torrents from strange sites, as there is a high chance they could be filled with Virus', or Malware or other dangerous programs for your computer.
This topic is for the English PATCH for Togainu no Chi, meaning you need to have the Japanese version of the game already installed and operational before downloading/applying this patch. There are currently no pre-patched versions of the game available, so you may be required to download the game through the normal non-torrent methods, and apply the patch on your own.
