I've got two Win7 (64 bit) computers here that already had Java 8 installed, but on both when I tried to run FoxTelem.exe it said that I didn't have Java and offered a link where I could download it.
However, double-clicking on FoxTelem.jar seems to work just fine.
Just thought I'd share that in case someone else runs into it.
Just went out to the driveway (EM72) to listen to Fox-1A fly over on a hand-pointed Arrow antenna. Great to hear it on-orbit. Didn't find any decoded telemetry on the "inside" computer (using an omni) when I came back in.
