To install technic launcher, you need to go to www.technicpack.net and click download technic launcher. Then it will say your download will start in a few seconds. Then find and open the technic launcher and enter your username and password like with the normal minecraft launcher. Next in the upper left hand corner there is a little box, click on that and scroll down to tekkit. Press login and it opens up like normal minecraft. You can either play on the morrowcraft tekkit server or play by yourself on singleplayer. ENJOY :D
