Wine is a free and open source application that aims to allow applications designed for Microsoft Windows to run on Unix-like operating systems. Wine also provides a software library, known as Winelib, against which developers can compile Windows applications to help port them to Unix-like systems.
Wine is a compatibility layer. It duplicates functions of Windows by providing alternative implementations of the DLLs that Windows programs call and a process to substitute for the Windows NT kernel. This method of duplication differs from other methods that might also be considered emulation, where Windows programs run in a virtual machine. In this article we are installing wine 1.7.25 version on Ubuntu 14.04.
