Hi Pablo,

If you use an older version of zint, maybe "isbn" instead of "isbnx" would work.

I have used both isbnx and qrcode successfully with zint 2.10 on linux.

\usemodule[zint]
\starttext
\barcode[alternative=isbn,text=9783865419026,width=4cm]
%\barcode[alternative=isbnx,text=9783865419026,width=4cm]
 \stoptext

Are you sure that you have the latest zint? (from sourceforge)
