Watchtower Library 2014 in Ubuntu

My system is Ubuntu 14.04.1 LTS
Here is what you need to install first.

1. You need "latest" wine, I use wine number 1.7.38, because with 1.6.2 it's not working.
2. You can download it here for 64 bits system and 32 bits system.

Then you install your package sudo -dpkg package_name.deb

Then install Watchtower Library.
