Yeah, changed the path, it still does it :/ Trying to reinstall Java 7. Properly, this time. I'll update later on what happens.

I see, thanks alot. I did a quick google search on how to do it, and while I did find some results, it says I am to add 'the location of the class to the value for PATH'. I'm not quite sure what to put there, could you help me out a little more? (I previously installed Java 7 and I figured it worked, but since it doesn't, I decided to try the other option)

System: Windows 7 64bit Java 64bit Anti-virus program: avast! Antivirus I downloaded the launcher and (after a few problems, they solved themselves mostly) it launches up fine. I choose a pack and login (it does the same thing for them all). The launcher closes (as it should), and opens up a new window. The new window then gets to the 'Mojang' screen, and simply shuts down without any error messages (it leaves a error message file on my desktop).
