Installing Wine....
What is Wine?
Wine" derives from the recursive acronym Wine Is Not an Emulator. Wine is a free software application that aims to allow Unix-like computer operating systems to execute programs written for Microsoft Windows. 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 not the ideal.Not all Windows applications run in Wine. And some that do require extra configuration in order to work. Wine implements the Windows API entirely in user-space, rather than as a kernel module at the time of writing
Installing Wine....
The installation of Wine is the same as for most software. These screenshots give you a basic overview of the steps. If you're unfamiliar with how software package management works in Ubuntu, you can find more details about it here.
Right-click the setup.exe for the Windows program you want to install. In this case, I went to the Sumatra PDF website and downloaded the installer file called SumatraPDF-0.9.3-install.exe and right-clicked it.
In the context menu that appears, select Open with "Wine Windows Program Loader"
To launch the installed Windows program, go to Applications > Wine > Programs and then find the menu item for the Windows program you just installed.
The program should launch and be ready for use!
