Minecraft 3D Installer

Download and open Minecraft.exe to run the game installer. Then just follow the instructions in the installer. You'll need an internet connection the first time you launch the game, but after that you can play offline without any issues. If you're planning on playing with friends, the easiest option is to start a subscription to Minecraft Realms. You can also set up your own Minecraft server from home, though that's a bit trickier to do. There are also a bunch of online servers elsewhere on the internet.
