: Always download launchers from their original community site (e.g., mcgroza.com ) to avoid "spyware" or malware associated with unofficial third-party clones.

: Some free launchers are bundled with extra software; always choose "Custom Installation" to uncheck unwanted "junkware".

: Ensure you have the correct version of Java installed (often Java 8 or Java 17 depending on the Minecraft version) for the launcher to execute correctly.
