WineHQ lets you run Windows software on other operating systems.
With WineHQ, you can install and run these applications just like you would in Windows.WineHQ (formerly a recursive backronym for Wine Is Not an Emulator, now just "Wine") is a free and open-source compatibility layer that aims to allow application software and computer games developed for Microsoft Windows to run on Unix-like operating systems. Wine also provides a software library, named Winelib, against which developers can compile Windows applications to help port them to Unix-like systems.
WineHQ provides its compatibility layer for Windows runtime system (also called runtime environment) which translates Windows API calls into POSIX API calls, recreating the directory structure of Windows, and providing alternative implementations of Windows system libraries,system services through wineserver and various other components the Windows Registry Editor. WineHQ is predominantly written using 'black-box' testing reverse-engineering, to avoid copyright issues.
