This problem is sending me nuts.
At the moment in my finder, .pkt files are associated to be opened with the wrong virtual machine. If I right click on a .pkt file and select Open With it says PacketTracer.exe - Wrong_windows (default). I want them to be opened and associated with my Windows XP machine.
I don't know how to change that default machine even though in the target Windows XP machine I associated all the files, even in the vmware taskbar icon in osx I associated them too with that XP machine, still no luck!
