I have been attempting to install Limewire for a week with this same problem.

I am able to choose the language and all other steps except for firewall preparation. It states.." some firewalls will ask permission for Limewire to use the network. You should allow Limewire full access.''

The problem is, this so-called window never pops up. And I don't know how to access it. So it just stays frozen on firewall preparation.

Can anyone please help me?
