I have downloaded an evaluation copy of uVision, and now I will try to se if I can compile some old software written for Keil 4.20. But my software relies on a header file rtx166.h which is not present. Why is it so? Is it because it's an evaluation copy?
rtx166.h is not for the tiny model. The tiny model relies on rtx166T.h which I have.
The RTX166 page tells you which products include it: http://www.keil.com/rtx166tiny/
