When I try to open the launch.bat file, it always gives me the error below (I didn't know how to post the actual pic of the error message, but I don't think it matters).

Error Messages:

'java' is not recognized as an internal or external command operable program or batch file.

Error Log:

Reinstall java, it's not a part of your PATH system variable so windows can't find it

It didn't work. I installed the same one I had before, JRE 7 Update 17.

Tried adding it to the PATH system variable. It didn't work. I just got a never ending error that kept repeating itself.
