Make sure your Java is up-to-date and follow these steps.

Test your Java path by openning Command Prompt and typing java to run.

It should result in a list of options and usage material.

When succeeded, run your Launch.bat file again.

The problem for you is that your computer is not registerring Java as a path command. So Command Prompt cannot open and use Java.
