I figured I should draw your attention to that only half of the download mirrors work, and of those that work none have the same file size or md5 as the one indicated. Furthermore, while 3 of the downloads are the same file, the one from betanews is even smaller than those, and I got 2 different corrupt installer messages while patching my windows installation source with it (which is what made me look into this anyway ). The rest seem to work fine though.
