I've used LaTeX for years, but I'm trying to work with ConTeXt now on a Win7
PC that has already had MikTeX 2.9 installed.
I've downloaded the minimal ZIP file, unpacked it and run the
first_setup.bat file.
(Note, I don't have Ruby installed yet, so I can't use pdfTeX, but I assume
some other build is available.)

Then I opened TeXworks, created a ConTeXt typesetting option, entered a
helloworld.tex program, and tried to ConTeXt it.

However, I just get these messages:

MTXrun | forcing cache reload

MTXrun | resolvers: skipping configuration file
'C:/Users/peterd/AppData/Roaming/MiKTeX/2.9/web2c/texmfcnf.lua' (no file)

MTXrun | resolvers: remembering file 'mtx-context.lua'

Any clues available?

Thanks!
