SKlauncher is an unofficial launcher for Minecraft, which, unlike the original, allows you to install and run more than one version of the game on your computer. It also allows you to customize many game parameters to your individual preferences. When you run the tool, you need to create a user profile where you can install the selected editions of the game.

SKlauncher supports Minecraft releases from 1.0 to the latest 1.12.2. Optionally, the user can also install experimental (so-called snapshots), alpha (2010) and beta (2010-2011) versions. SKlauncher also allows you to create any number of player profiles, define game locations, resolution, and select a location with the javaw.exe component required to run and add arguments for JVM.
