The launcher acts as a wrapper that bypasses the standard Microsoft Store restriction of having only one version of Minecraft installed at a time. Version Management
: It allows users to download and register specific Minecraft versions (Releases, Betas, and Preview builds). Parallel Installations
: You can test new beta features or play on older versions for specific server compatibility without needing to constantly uninstall and reinstall the game. Clean Organization
: The interface is divided into tabs for "Release," "Beta," and "Imported" versions, making it easy to see what is currently installed. Setup Requirements
To use this launcher effectively, you must configure your Windows environment: Developer Mode : You must enable Developer Mode in Windows Settings ( Update & Security For Developers ) for the launcher to register the game packages. Prerequisites
: You typically need a legitimate copy of Minecraft Bedrock already owned on your Microsoft account. Some users recommend installing the standard version from the Store first to ensure all necessary system dependencies (like DirectX or VC redistributables) are present before using the custom launcher. Permissions
: Running the launcher with administrator privileges is often required to avoid "permission denied" errors when registering new game packages. User Experience & Technical Challenges

Newer versions (0.6.0+) support GDK versions of Minecraft (1.21.120 and up). Simplified Modding:

While you can have many versions installed, you can only run one instance of the game at a time. Data Management:
Worlds and settings are shared across versions unless you use a profile manager like FoxyNoTail's Version Switcher , which can sometimes be used in tandem with this launcher. Common Error ("Re-register failed"):
If the game fails to launch, try moving the launcher to a different directory or ensure Developer Mode is definitely on. GDK Admin Risk:
Some newer GDK versions of the game may automatically run as Administrator when launched through this tool, which can affect how some external mods or debuggers interact with the game. MCMrARM/mc-w10-version-launcher - GitHub 16 Dec 2025 —
