[Koha] Koha 3.0 beta

I understand Koha ver 3.0 beta can work on windows and I have tried to download this verson so many time and can not locate the installation file in other words the setup file. Can someone please help or maybe there's something missing out. regards -- Noel Peter Kalonga ICT Technician The Catholic University of Malawi Montfort Campus P.O Box 5452 Limbe - Malawi Cell: 09 313 984 Other e-mail: nethwpeter@hotmail.com noelkalonga@yahoo.co.uk noel@technologist.com cathNkalonga@africa-online.net Nkalonga@cunima.net
