title: cygwin installation
body: <p>i am trying to install cygwin on my laptop running Windows 7 64 bit.
  according to the official site, it is recommended to download and install individual packages as it takes much time. so i installed one by one but the problem is that at the end of every installation, an error appears. "Download incomplete. Try again?"
  is this doing it because i haven't installed all packages or because the download for the package i chose was incomplete/unsuccessful?
  if the latter, how can i fix this problem?</p>
  
  <p>i am downloading from the mirror sites. <a href="http://mirrors.xmission.com" rel="noreferrer">http://mirrors.xmission.com</a> and <a href="http://mirrors.kernel.org" rel="noreferrer">http://mirrors.kernel.org</a></p>
