The error message you are facing is not Octave related [1], something in
your Windows (maybe invoked by Octave?) goes wrong. To get your situation
right:

1. You successfully installed Octave 4.2.0 to C:\Octave?
2. You can run the GUI and evaluate simple commands like `1+1`, etc.?
3. You can neither install any packages `pkg install xyz` nor list them `pkg
list`?
4. The command `path` does not work either, does `pwd` (current working
directory) work?


Basically the `pkg` command queries these two directories:

local_list = tilde_expand (fullfile ("~", ".octave_packages"));
global_list = fullfile (OCTAVE_HOME (), "share", "octave",
"octave_packages");

Do these expand to `C:\Program Files...`? Otherwise you can try

edit pkg

set a breakpoint in the editor and step (F10) through the code until the
error occurs.

HTH,
