The Netflix Desktop site below which you probably should have read before beginning. It states specifically that it is not compatible with "vanilla" Wine, so installing the package will uninstall any existing Wine installation. So did you already have wine installed or did you install wine separately? If so, you will likely have problems. Note also on the page they recommend the newer repository, PPA:
sudo add-apt-repository ppaipelight/stable
You need to enable Silverlight which is explained in the link I posted above and you also need to have your browser identified as a windows browser. That is also explained in the second link from my previous post.
I have used the method I suggested to install successfully wine-pipelight on Ubuntu 12.04, 14.04 and Mint 17 so I know it works. I never used the Netflix Desktop software so don't know how well that will work.
