4.1 Requirements

• Operating environment: Microsoft Windows XP SP3, Vista SP2, Windows 7, or Windows 8 (including x64 but not IA64 versions). Windows Vista or later is recommended.
• For interfacing with C or C++, or for using spld or splfr: C compiler and related tools from Microsoft Visual Studio. The version of Visual Studio should match the version used when building SICStus Prolog. For this reason a number of variants of SICStus Prolog is released, each built with a separate version of Visual Studio.

  Microsoft offers free editions of Visual Studio and its C compilers. It is probably possible to make these work as well but they may require other tools or downloads.

• For distributing products incorporating SICStus Prolog runtime systems: SICStus Prolog depends on the C runtime library corresponding to the C compiler used when building SICStus Prolog.

  There are several alternative ways to have your installer install the Microsoft C libraries. See the Microsoft documentation for details, or contact SICStus Support.

  Building installers for Windows (or for any platform) is complex. There are several tools available, some of them free, that can help with the task. The SICStus Prolog installer is built using the free WiX toolset from Microsoft.
