Why does my Minecraft launcher keep crashing when I press play? [duplicate]

Whenever I press play on my Minecraft launcher it starts to load, then goes back to the launcher.

This is what it tells me:

Java could be corrupted. A fix for this:

1. Press Windows Key + X.
2. Select Programs and Features.
3. Press F3 key. In the Search box on the top right corner, type “Java”
4. Right click “Java Runtime Environment” from the Search Results, select Uninstall option.
5. Follow the on-screen wizard and then reboot your PC.
6. Reinstall Java from here

This could also arise due to conflicts with the User Account Control (UAC), a security feature in Microsoft Windows. You could try disabling UAC:

For Windows 8.1/ 8:

1. Press Windows Key.
2. Type “Control Panel” in the Search Box.
3. Click the Apps icon.
4. Open that from the Search Results.
5. Click User Accounts and Family Safety | User Accounts.
6. Click “Change User Account Control settings” link.
7. Move the slidebar to the extreme bottom, i.e. Never Notify.
8. Click the OK button.

For Earlier Versions of Windows:

1. Click the Start button.
2. Type “Change user account control settings” in the Search Box.
3. Open that from the Search Results.
4. Refer Steps # 7-8 from Windows 8.1/ 8 user’s paragraph.

If you need more info, or don't have Windows 8, go to the original article.
