Hi Pavel,

What binary have you tried to run? One that you compiled or one downloaded 
from CGAL website?

It seems that Qt4 is installed on your machine, and that version of Qt4 has 
been compiled with mingw. Binaries that you can download one the CGAL website 
cannot be mixed with that version of Qt4. Check what you have in your path.

The easiest way to run CGAL precompiled demos is to put the "all demo dlls" 
in 
the same directory as the demo itself. That way, you are sure that the 
dynamic 
linker of Windows will found the correct Qt4 DLLs.
