Thanks to Lukas and Mojca too for the reply. 
The problem may be elsewhere. At my working computer (at work) I have Windows 8.1, and there I ConTeXt standalone installed ok and everything works as it should. On my own laptop I install Windows 8.1 Enterprise (ie. I think the top product) and even ConTeXt not installed because the installation procedure did not find DLL. At the moment I do not know what it could be. Maybe when I install the drivers (I had trouble installing the graphics driver) something screwed up. Perhaps it wanted a broader discussion of Windows 8 users, respectively. 8.1 and probably even different versions (Home, Professional, Enterprise ???).
Thanx
