Today tried using winget to see how it works for installing SWI-Prolog.

```nohighlight
C:\Users\Groot>winget search swi-prolog
Name Id Version Source
------------------------------------------------
SWI-Prolog SWI-Prolog.SWI-Prolog 8.4.3 winget

C:\Users\Groot>winget install swi-prolog
Found SWI-Prolog [SWI-Prolog.SWI-Prolog] Version 8.4.3

```

AFAIK the code that sets up [NSIS](https://nsis.sourceforge.io/Main_Page) (Nullsoft Scriptable Install System) for SWI-Prolog is in

> <https://github.com/SWI-Prolog/swipl-devel/blob/2c1b8076b959e7962c9f5254bbbe38bca52fd901/cmake/Pack.cmake>

which is causing `Installer failed with exit code: 2` If one downloads SWI-Prolog for Windows, starts NSIS installer and tries to uninstall a currently installed version when prompted they will see the installer failing as noted in the previous [post](https://swi-prolog.discourse.group/t/wiki-discussion-install-swi-prolog-development-version-on-windows-10/2602/7).
