Have you ever used SpatiaLite on Windows? If so, how did you install it?
The MS Windows Binaries on https://www.gaia-gis.it/gaia-sins/ give you the options in the first screenshot, linking to the files in the second screenshot
Which of mod spatialite-5.1.0-win-×86.7z or spatialite-tools-5.1.0a-win-x86.7z did you download, what software did you use to decompress it and what did you do with the files inside those .7z files?
Asking because I want to bulk up Datasette's SpatiaLite installation documentation
I'm not very Windows literate these days. Am I right in thinking that Windows doesn't include the ability to open .7z files by default, so you need extra software? What extra software do people generally use for that?
