I cannot, of course, see what you are clicking on to try to start the program(s), but all of the EXE files for any version of iGo are indeed "WinCE" programs.
I suppose it may be possible that your device has somehow been made 'proprietary', and can only run specialized software, but I have never seen such a thing. Not with a WinCE device, anyway.

I stand corrected on that issue. Never heard of such a thing.
Oops.
