Currently, you can go thru a link on the Project Open site:
http://sourceforge.net/project/showfiles.php?group_id=86419
On that page is a link to the Windows installer mentioned.
I have installed it with the OpenACS option (even though it says _for experts only_) as I wanted a _bare bones_ OACS install, rather than the pre-configured Project Open one. I am happy that option exists. Thanks, Frank and Vlassis.
