IMPORTANT! You need Icaros Desktop 1.1.1 already installed! I haven't tried with 1.1.0 and I don't warrantee it will work at all.
a. download wherever you like, for instance RAM:T
b. open a shell
c. enter these commands
d. wait some seconds and reboot
(you can also simply double click on the archive icon to extract files, and doubleclick on the Installer one to install)
Since it won't be added to AmiStart automatically, you'll have to run it from the Tools/LUPD directory with Wanderer.
> Download LiveUpdater 1.5.1 (1,5 MB, zip file format)
When Icaros Desktop 1.1.2 update will be available, LiveUpdater will download and install it for you.
