Bad video card drivers!
-----------------------
Minecraft was unable to start because it failed to find an accelerated OpenGL mode.
This can usually be fixed by updating the video card drivers.

Having same problem but on my XP 32bit

Either you should update your drivers or your card is too old to even support OpenGL and thus you really shouldn't be trying to even launch minecraft.

To update them its really easy, just open the start menu, right click computer, go into properties, click device manager and find your display adapters, open that up right click the one inside it and do update driver software and make it look online for software.

NOTE: this is win 7 and vista
