How to download the game?

[Zapcat56]

I want to play this because I finally upgraded from a potato pc, but every time I click play I just get a download of a file with a bunch of random stuff in it, heres the stuff in that random file (yes I am going to copy paste it) and I have no idea how to actually play the game:
<?xml version="1.0" encoding="utf-8" ?>
<jnlp codebase="http://game.havenandhearth.com/java/" spec="1.0+">

</resources>

Nice hobby, shuffling through official stupid questions section aka "How Do I" and pointing out stupid questions, mocking noobs for being noobs. Is good for post count, yes. Too bad is only for those who popped out of the womb perfectly versed in all conceivable videogames, software, hardware and general information, and didn't ever had to ask a single question.

In all seriousness, there is such thing as "exceedingly stupid question", which has a very high chance to be trolling and shitposting, like, for example, if someone asked how to turn the computer on in order to play h&h. This is, obviously, not the case.

But he has a point.

I suggest we let this thread die now and leave the corpse as something future archeologists can wonder about.
