[NTG-context] Problems with the installation of the minimals on Win XP :-(

Hi, after solving my problems with the minimals with Linux, I have now a problem with the Windows version. :-( My boss allowed me to use ConTeXt for a book project :-), unfortunately we work here with WinXP and the first-setup.bat fails with the following error: mtxrun.exe – Komponente nicht gefunden (mtxrun.exe – component not found) Die Anwendung konnte nicht gestartet werden, weil kpathsea60071.dll nicht gefunden wurde. Neuinstallation der Anwendung könnte das Problem beheben. (Couldn’t start the application. Couldn’t found kpathsea60071.dll. A new installation of the application could solve the problem.) I have installed ruby first. What could be wrong? Greetings Florian Baudach
