You do realise that 3.1.50 is meant for Octave developers and not for 
users, right? You probably should use a release from the 3.0.x series -- 
they also come with most packages pre-installed.

Yes, no packages are provided in the developer snapshot you downloaded.

You should click 'save' such that you just download the file. Assuming 
you download the file to C:\   (probably not a good place, but I don't 
know much about windows), then you can install the package by typing

 pkg install C:\nnet-0.1.8.tar.gz

from within Octave. Then the package should be installed. This, however, 
assumes that the package only contains m-files. If something needs to be 
compiled, you also need to install a compiler. But that's a separate 
problem...

Cheers,
