You keep talking of "downloading" and "unpacking" things.  That 
indicates a continuing misunderstanding of how Cygwin is supposed to be 
installed and configured on your machine, and has been the cause of 
rather a lot of the confusion you've been going through.

You should never be doing any of that yourself.  You simply (re-)run 
Cygwin setup and select which packages to install.  As such, the process 
is really a case of "installing" things.  Downloading, unpacking and all 
that is handled by the setup program and its underlying database of 
packages and their relationships.
