Yes, I looked at the video, and ran the file from Command Prompt, and got the exact same error as thenecroreaper. I don't know where to put the -Xmx1024M. Do I insert just that one piece into the java command?
I am having the exact same issue as above but I'm not sure what to do with Lex's comment. I am a non-programmer mom trying to install this for my 10-year-old son. Thanks in advance for your help!
