Didn't work, I'm still getting the same problem.
By "didn't work" do you mean that double-clicking on the DiceTool jar file failed to launch it?
I'm wondering if it's an issue of it trying to open with the wrong program, is it supposed to open with Java SM Binary?
Do you mean Java SE
If so, then, yes. But it shouldn't even be asking you if Java is installed correctly.
When you look at the DiceTool directory does it look like this?

Note the little Java coffee cup icon for the DiceTool jar file? Does yours look like that?
I would like you to open a Command Prompt. From your Start menu go to All Programs and then Accessories. Command Prompt should be fairly close to the top of the list.
Once it is open, click in it and type "java -version" and then hit Enter. If your Java is installed correctly then you should get back a response like this:
java version "1.6.0_22"
Java(TM) SE Runtime Environment (build 1.6.0_22-b04)
Java HotSpot(TM) 64-Bit Server VM (build 17.1-b03, mixed mode)
Yours should say "1.6.0_23" for the version.
