Download the torrent for Minecraft 1.7.9 here. Some older versions: 1.7.8 – 1.7.7 – 1.7.5 – 1.7.4 – 1.7.2. You will need a BitTorrent client like uTorrent to use these files. After you have installed uTorrent, open the torrent file and uTorrent will automatically begin the Minecraft download. Once the download is done, double-click the completed torrent and run the installer. Once finished installing, you can create a profile, set a username, and begin playing.
All Operating Systems
Instead of using torrents, you can instead download Minecraft SP here. Run the .jar file and a cracked launcher will load. Next, enter a username, tick the “Force Update” box, and click on “Enter Game”.
