I did exactly that. The sanme thing happened. After half an hour of zero disk activity, I cancelled the install. This time, I was left with a Comodo Dragon icon on my desktop, and an entry in add/remove programs. Hoowever, when I tried to uninstall, I got a message that it had already been uninstalled. I'm not sure what Comodo Dragon is, I don't need it, all I want is the firewall. Is there some way I could get just the firewall and see if it installs?
