Step 1: Download and install the latest release version of Java. You can find it at
www.java.com. (Note: it might be better if you get the 64-bit version as most browsers are still only 32-bit and that's the version you get from the auto-detection. Find at
https://www.java.com/en/download/manual.jsp). Be sure to restart your browser after installing Java.
Step 2: Click the play button. This will download a small file called "autohaven.jnlp" which should automatically open using the Java software you just installed (if you clicked 'run,' else it will be saved to where you put it, and you should be able to double click to open).
If you have other issues, please post any errors you get or describe the issue in detail. Please let us know the version of Java you installed, the operating system you're running and version number, and we may need other information for troubleshooting.
