Minecraft Crash on launch?

To get more detailed info on what happened and why, we'd need the log that the game said was written to C:\Users\Daniel\Appdata\Roaming\.minecra…
However, I'll run you through some of the more basic errors here.
Try updating your java first. This is by far the most common problem with Minecraft launching. Updating your graphic card's drivers will also help. Your computer might also have too few resources to run the game. In that situation, go to Optifine.net and download Optifine. This will make Minecraft load better on your computer, hopefully fixing the issue. If nothing else works, you'll have to contact Mojang for a fix, or put the error file it saved here.
