## 4 Release Notes and Installation Guide for Windows

This chapter assumes that the environment variable `PATH` includes `%SP_PATH%\bin`, where `SP_PATH` points to the SICStus installation directory (typically C:\Program Files\SICStus Prolog VC14 4.3.5\). Here, `%SP_PATH%` is just a place-holder; you usually do not need to set the environment variable `SP_PATH`, but see CPL Notes in the SICStus Prolog Manual. For example:

```C:\> set PATH=C:\Program Files\SICStus Prolog VC14 4.3.5\bin;%PATH%
```

To use `splfr` and `spld`, you must also set up the appropriate Microsoft Visual Studio tools; see Setting up the C compiler on Windows in the SICStus Prolog Manual for details.

To use the respective library modules, you must also include the paths to Tcl/Tk (see Tcl/Tk Notes) and Berkeley DB (see Berkeley DB Notes) onto the `PATH` environment variable if the installer for Berkeley DB and Tcl/Tk have not done so already.
