pi3 & piaware not working

Having loads of trouble getting my pi3 to work with piaware… I’ve tried a dozen times… nothing!
Now I’m trying to load the piaware software again, and I get a dialog box with 4, “/dev/disk…” choices (tried inserting a screen shot but didn’t take)
Anybody know which disk I have to choose?
Regards

We need more information.
What are you using, a Piaware image or an image from raspberrypi.org(if so which image? Jessie or Wheezy. Only Jessie with work with an RPI3).
Are you following the instructions on flightaware.com/adsb/piaware/build section 2.
Are you burning the image to the SD card, not just copying it?

Are you using add-on programs like this setup flightaware.com/adsb/piaware/install

What are the error messages, if any?
