Trouble installing RSBuddy

[BuzzerBeater911]

I downloaded it from the site, and I got the .jar file, but when I open it, it asks me how to open it. It says look on the internet for a program or select one myself.

EDIT: Fixed it. Simply installed java and it works. *facepalm*

Yeah, you'd need java for it to work.
