Downloadable VOR/ADF simulator?

Greetings!

I'm taking my CFII checkride at the FSDO tommorrow and since I'm taking my
laptop along with me, I thought it would be cool to have a VOR/ADF
simulator/trainer loaded on my computer to use as a teaching aid. Since
internet access won't be available, I'd like a some sort of freeware app
that I can load locally. I've checked out the web based java applets on
Ryan Ferguson's site (by Roy Epperson), as well as Tim Carlsons applet
(which by the way, I download the nav.zip file off of his site to run
locally but it doesn't work??).

Anybody have any ideas?
