AB Commander is designed for Windows 10, 8, 7, Vista, and Windows Server (2008 or later). AB Commander can be used with both 32-bit and x64 editions of Windows: the setup utility automatically installs the 32- or 64-bit executables of AB Commander, depending on your version of Windows. AB Commander may still work with Windows XP or Windows 2000, but we no longer support such combinations. AB Commander is NOT compatible with Windows 95, 98, Me, Windows NT 4.0 or any older version of Windows.
There are no special requirements or recommendations except the obvious one: the better processor and more RAM your computer has, the better AB Commander will perform.
