They have specifically dropped support for Windows -- it has been mentioned a few times on this bboard -- use the search.
Now, there were a few unofficial aolserver-win32 compiles (check the new-file-storage), but they are just that UNofficial (though i do use it for development purposes).
If you do do search on this bboard, you will see that there are problems with win32 aolserver -- file up/downloads aren't working well, it's a pain to make it use graphviz, etc.
Bottom line -- you should NOT use it for production system.
