I bet this the 32 bit hosted.
Does 32 bit hosted work on 64 bit linux?
Yes, absolutely. You need to have 32bit libraries installed, though. I have just modified Icaros installation script for the 32bit version to handle this case. Unluckily, this hasn't been released yet:
sudo apt-get install libxxf86vm1:i386
sudo apt-get install libxcursor1:i386
sudo apt-get install libasound2:i386 libasound2-plugins:i386
