I will just add to the excellent answers above, that I very much
recommend LMTX and the LMTX way of using the zint _library_. I published
compiled versions of zint and couple of other libraries to the optional
libraries repository:
https://github.com/contextgarden/luametatex-optional-libraries
https://github.com/contextgarden/luametatex-optional-libraries/releases/tag/v20230902
I tested the steps on the wiki and libzint.dll works without problems:
i.e. install ConTeXt, create a few folders, move the dll and
mtxrun --generate.
My goto document for testing zint, that went without problems (even the
hexagons!):
\starttext
\usemodule[zint]
\barcode[alternative=isbnx, text=9783865419026, width=4cm]
\barcode[alternative=qrcode, text={https://wiki.contextgarden.net},
width=3cm]
\barcode[alternative=maxicode, text={test}, width=3cm]
\stoptext

PS: Coincidentally zint 2.13 has been released just today. Usually every
new zint release requires an update on the ConTeXt side, but older
releases still work well with ConTeXt (e.g. currently ConTeXt supports
2.10, 2.11 and 2.12). The version linked above works.
