Just uninstall Java, and start the T Launcher Installer again. It´ll mention that you need Java, and will ask for your permits to download it. This way, the installer will search the adequate Java, and it won´t be hard for you.

Solo desinstalen Java, e inicien de nuevo el instalador de TLauncher. Les indicará que necesita Java y te pedirá permisos para descargarla. Así, el instalador buscara el java adecuado, y no les será tan difícil.
