I found three links in the forums.
http://download.comodo.com/ctm/download/setups/client_setup_2.9.161985.187.exe (beta)
http://download.comodo.com/ctm/download/setups/client_setup_2.8.155286.178.exe
http://downloads.comodo.com/ctm/download/setups/client_setup_2.6.138262.166.exe
I tested all these links and they download.
