Is it possible to start Alice with MultiMC? I always get an error. this method doesn't work for me anymore: http://skcraft.com/threads/alternative-login-method.2710/
Since we are updated to 1.6.4 (which includes various changes to the way launching the game is handled), the method listed on that page does not work anymore. Please use the new client from http://www.skcraft.com/welcome.
