Hello inandi2015, and welcome to the forum!
Make sure you have your platform type set to 'Lego NXT + TETRIX/MATRIX' in order to enable the FTC templates. You can change your platform type by navigating to the Robot menu and selecting Platform Type->Lego Mindstorms->Lego NXT + TETRIX/MATRIX. Once that is selected you should have the option to open a new Autonomous or User Control Template.
Please let me know if this solves the issue for you.
