Hi,
I have released the first alpha of the new 0.9 Kiwix branch. The most important improvement is that the Windows support is back.
You can download here the client and the sources: https://sourceforge.net/projects/kiwix/files/
Have also prepared an "all in one" ZIP, with the WP1 0.7 selection (30.000 good and important articles): http://tmp.kiwix.org/tmp/kiwix-0.9-alpha1-win+wp1en0.7.zip
Other Zim files may be downloaded here: http://tmp.kiwix.org/zim/0.9/
Enjoy Emmanuel
