I have problem with Cisco Packet Tracer.I have v. 6.0.1 and Ubuntu 14.04 64bit. I would like to know how fix it. When I use command /usr/local/PacketTracer6/packettracer to run PT I see only Starting Packet Tracer 6.0.1. When I click on the Packet Tracer in Dash - nothing happens. Help me. I need this program for study. I thought, probel is with 32bit program on 64 bit ubuntu, so I find this site _iraf.html. I install lib32z1 lib32ncurses5 lib32bz2-1.0 but again nothing. And I sorry for my english but I wasnt born in english-speaking country.
