If you don't have the patience to LEARN about a new and different OS then go back to XP or get a Mac and run OS 10.4. They are more mature and have thousands of programmers to work on them to make them IDIOT FRIENDLY. The later Amiga OSes have been developed by a handful of dedicated and talented programmers that have worked for the love of this platform as much or more than any money they might have made from their efforts. Your complaint is about the program you are trying to load, not the 3.9 OS itself and again, Amiga programs are mostly done by a small group if not just one or two programmers that may, or may not have spent a large amount of time making the installation process IDIOT PROOF.
From your comments, you may not be the type of person that can appreciate what the Amiga is and what it can do. The Amiga computer of today is not for the masses that have little experience with setting up and tweaking computers to get advanced performance from less resources than multi-gigahertz processors and 1 to 2 gigabytes of RAM that can run the bloated and inefficient operating systems from Microsoft or Apple.
Like the man said, learn about what you are trying to use before you start calling it crap, or we will all just assume that you are the IDIOT I have mentioned above that should stick with XP or Mac OS 10.x
