Put the summary of the bug you're having here

*What I expected to happen was successfully playing minecraft
*What I thought would happen is after clicking the 'Play' button in the launcher, Minecraft would load so I could play it.
*What actually happened was instead of going to the minecraft menu screen, (with the option of selecting singleplayer,etc) I was directed to the game output area of the launcher. I think this line of text in the launcher log is important:
Caused by: java.io.IOException: Create Process error=2, The system cannot find the file specified

Describe what happened here
I clicked the 'Play' button in the minecraft launcher and was directed to the game output page of the launcher instead of the actual game.

Steps to Reproduce:
1. Launch minecraft with Windows 7, Java version 8, and any minecraft version.
2. Click on the 'Play' button in the launcher
3. The game doesn't load, so you can't play it.
