Thanks for the hints. Unfortunately, none of them has worked. I tried cleaning Local Settings/Temp dir, running Setup.exe from different location, creating a new user. It always ends the same way: a hourglass pointer appears, there is a window opening for a fraction of second and immediately closing (so just the outline of the window can be seen, no content).

I will survive without it, At home I use XP machine which has no problem.

regards, Michal.
