Be sure to look at the entire file as much of the NSIS details are not shown in the sample and further along in the code.

Be aware that for the [NSIS](https://nsis.sourceforge.io/Main_Page) install of SWI-Prolog on Windows there is currently a problem if one picks the uninstall option during the NSIS install. ([ref](https://swi-prolog.discourse.group/t/wiki-discussion-install-swi-prolog-development-version-on-windows-10/2602/7)). To avoid the problem just do not try to uninstall SWI-Prolog on Windows using NSIS when given the option. Installing SWI-Prolog on Windows with a current install has not caused any problems I am aware.
