Users of Icaros 1.4.x who had already downloaded any 1.5.x version, but not installed it, please download again a patched version and use it instead of the old one.
Users of Icaros Desktop 1.5 who have not already installed any update to 1.5.1, please download the patched version of the 1.5 > 1.5.1 update pack and install it with LiveUpdater
Users of Icaros Desktop 1.5.1 (or 1.5 updated to 1.5.1), please download patch 01 and install it with LiveUpdater
Users of Icaros Desktop 1.5 LKE, please download the patch 01. It applies on 1.5, 1.5.1 and 1.5 LKE indifferently. Do NOT install update from 1.5 to 1.5.1, because newer system files can't apparently work with older ones.
