They should download java 7 because java is needed to run jar files. When done, run the launcherXXX.jar file.

Occasionally an overzealous archiver decides to handle jar files (instead of letting java do that) as jar files are glorified zip-files. So if you install such an archiver *after* installing java, you need to fix the "default handler".

Has the Windows 8.1 machine got Java 8 installed?

If so that may be the problem. I have just hit that same issue.

I was attempting to use the online instance only to find that Java 8 blocks the use of self-signed applications even when the site is added to the Exceptions list for Java security. :evil:
