[NTG-context] Problem with installing ConTeXt

I am still struggling to get ConTeXt running under Windows. At home where (when I work with Windows) I work with Vista it worked. At the company they use XP. I did the same as I did at home, but now I get error messages about configuration files that can not be found in the non existing directory c:\contextminimal. I installed ConTeXt in c:\context. Is it possible that something changed since yesterday? The way I try to couple ConTeXt and TeXworks is described in the following document: http://www.decebal.nl/ConTeXtManual.pdf -- Cecil Westerhof
