My Minecraft won't work at all how do I fix it?
Whenever I click on my minecraft to start it, it doesn't go to any screen but a small box that says "The registry refers to a nonexistent Java Run-time Installation or the runtime is corrupted.
The system cannot find the file specified" Help?
You might not have a JRE installed. It would really help if we could see a crash report or something. Try re-downloading java and see if that fixes it.
