The file "default.br4" is one that Bryce looks for when it launches, but is not included when Bryce is installed. Just make a scene with all the settings you want to start with, and save it as "default.br4" in the same directory as the Bryce program. Here's another tip. - You can make more than one default file if you have a few modes that you might like to use. You can save camera dots (views), screen resolutions, sky settings (and saved sky dots) - now just save the file as "default-2.br4", or whatever you want to call it, into your main Bryce folder. Bryce will still open with "default.br4", but you can open any of these other defaults anytime you want, to start a new picture.
