Legacy Launcher

Extreme Launcher started as a hobby project born from the need for a simple way to manage multiple Minecraft instances.

While the jump from v3 to v4 brought major improvements and a cleaner codebase, maintaining and updating it became increasingly difficult. With latest v4, we've rebuilt the launcher on the modern .NET 6 platform. It now includes automatic Java installation, broader mod support, and many new features to enhance the overall experience.

Versions prior to v4.0.2.0 are now considered legacy and will no longer receive updates.

For Minecraft 1.16 and earlier, Java 8 is recommended. Starting with 1.17, Java 16 or higher is required. For 1.18 and newer, Java 17 or higher is mandatory.

ExtremeLauncher v4 requires the .NET 6. Most Windows systems already include this, but if not, you can download it from Microsoft.
