Cannot play game

Is it browser-based? Would running the Edge browser prevent it from running? It downloaded "autohaven" but cannot recognize that file. UPDATE: I checked Firefox and the same thing. What I have not tried is loading java with the arguments listed in another post, how on earth do I run java with arguments?

You need to install Java. Be sure to download the most appropriate version for your operating system. https://www.java.com/en/download/manual.jsp

Update: Apparently Edge browser nor Firefox wants to run Java. I dug around and found Internet Explorer 11 in the windows files, and Java is currently installing. We should be up and running in minutes. I could leave this here in case someone else has the same trouble, or you could delete if you deem frivolous. I could not find this solution online with the usual methods.

What browser you're using shouldn't matter at all. JNLP programs run completely independently of the browser, just like any other program that is not the browser. If the error you're seeing is that Java can't install the browser plugin, then you can safely ignore that, since that's just for applets.

There is ONE problem you can run into. If "Enable Java content for browsers and Web Start applications" isn't set, then Java won't properly launch .jnlp files (won't associate javaws.exe with the .jnlp extension). This can be fixed by opening the Java settings (Windows: Control Panel>Java), going to the "Security" tab, and setting the option to "checked."

edit: I think Chrome would actually have more issues with Java than Firefox or either MS browser due to some of the recent changes to support for legacy standards being removed.
