I have installed Italc 2.0.0 (64 bits) on 14 Windows 7 64 bits PC. Most features work well except demonstration either in full screen mode or windows mode.
It works for a while. Then either ica.exe or italc.exe crashes on teacher's computer or a timer appears on client's screen (with a black background) waiting for the connection to be established. I tried many things : changing Symantec Endpoint Protection firewall rules, desactivating the firewall, changing the demo server backend but in vain.
