I have java on my computer, but when given the open/save option during installation my computer has no programs on it that can open the file....which program should I download in order to run this? Preferably something free

Hello D E M O N S,

Please download and install Java 8. Once you have completed this, you should be able to just double-click the launcher, or right-click and select "open with Java Runtime Environment".

Regards,
