All,

I don't have the very latest Miktex, but a reasonably new one (Miktex 2
with Update 1). I unpacked the new Context beta (texexec.ini attached) and
used Miktex Options->Tex Formats to build formats for pdfelatex and
pdfetex, refreshing the filename database whenever I could.

texexec --make

seemed to go well (I have the eformats in \localtexmf\miktex\fmt. But when
I compile this sample file,

\starttext \framed {Let’s see if it works.} \stoptext

I got this error message:

F:\ConTeXt\MyWork>texexec junk

 TeXExec 2.5 - ConTeXt / PRAGMA ADE 1997-2001

This is pdfeTeX, Version 3.14159-14f-released-20000525-2.1 (MiKTeX 2 UP 1)
initexmf: don't know how to dump miktex

I can't find the default format file!

Has anyone experienced this before and know how to cure the problem?
