--- Comment #19 from Frédéric Delanoy frederic.delanoy@gmail.com 2013-06-08 04:32:58 CDT --- Couldn't find any download link for latest joost (1.1.8 beta) [joost has been discontinued].
Tested with a 0.8.0 version which started correctly (albeit asking for updates).
Can someone please retest with a more recent Joost installer version?
