When using the Launcher it goes as far as showing the mojan screen and changes the icon on the task bar to look different to the launcher Icon. Then it crashes and goes back to the launcher - and in the development tab I get a Java Run time error and referred to a file on my system that holds the details for reporting bugs.
the error is as per attached text file
I have gone to the Mojang Technical website and used the checker there and this just refers me back here to the Minecraft BUG REPORT JIRA system saying my bug hasn't been reported yet.
The Intel 4 Series (and older) video cards are unable to play 1.7.4 and future versions of Minecraft. You will need to buy a new video card or computer to play new versions.
For now, you can still play 1.7.2 or older versions of the game. To change your game to a different version, start the launcher. Select Edit Profile. In the "Use Version" dropdown menu, select the game version you want. Then click Save Profile.
You can try your luck and update your Graphics Card Drivers as some chipsets are still supported. If that doesn't work, then the first part of this applies.
