How to Install "Minecraft"by Shea Laverty ; Updated September 22, 2017
To get to building and smashing your own cubical world in "Minecraft," you need to first download and install the game. Unlike most other software, where you download an installer program and run it, "Minecraft" uses a "game launcher" client to download all game data and install it, including updates. This adds some extra requirements for installing "Minecraft" that most other software doesn't have.
Minecraft Game Client
Once you've purchased "Minecraft," you can download the game client. This program works as both a means for launching "Minecraft" and for downloading and installing game files and updates. The client itself will install fairly quickly, at which point you can run it and begin downloading the actual game files for "Minecraft." The actual download and installation will likely take a bit longer, depending on the number of updates available when you begin downloading and your Internet connection's speed.
Requirements for Installation
First, you'll need a Mojang account to purchase and download the game. The "Minecraft" client runs on a Java platform, so you'll need to download and install the latest version of Java before running the client's installer. Once Java is installed and the client is ready to go, you'll need a stable Internet connection until all files have finished downloading and you've logged in at least once online. After that, you can play single-player games of "Minecraft" without an Internet connection.
