On Windows, the system looks for required DLLs in the same directory as the
executable first. Good installers will thus install their required DLLs to
the same directory as the executable. This prevents pollution of the system
DLL directory, and insures that your application will use the DLL it shipped
with, rather than some version written by something you installed later. So
there's not really any "DLL hell" if you install DLLs to your application
directory. This is one thing Windows got right.
