What should happen:
the game should run after I click play.

What happens:
Well when I press play the Minecraft launcher goes away after downloading some stuff then comes back with (under a new tab of Game Output):
Completely ignored arguments: [--nativeLauncherVersion, 307]
[22:27:53] [Client thread/INFO]: Setting user: Laurent123
[22:27:57] [Client thread/WARN]: Skipping bad option: lastServer:
[22:27:57] [Client thread/INFO]: LWJGL Version: 2.9.4

Launcher Log:
[22:28:22 ERROR]: Game ended with bad state (exit code -1073740791)

Also on top of my Launcher it says MIncraft Launcher 1.6.73 ,not 1.6.66.

Step to re-make problem:

1. Run Minecraft
2. Press play
3. Wait
4. Error
