Firewall for Vista64

This is a 2 parter. First, I can't seem to find a freeware firewall that works with Vista64. I tried ZoneAlarm and Comodo, and neither would install on my system. Can anyone recommend a firewall that will work for Vista64?

Next, I installed VistaFirewallControl 2.1 yesterday, but I'm a bit confused as to what it actually does. From what I've read, it sounds like it works with Vista's own firewall, and they can both co-exist in the same system without any problems. I checked out the controls, and I'm too much of a novice to figure it out. Can someone please enlighten me on this? Thank you.

 

I'm running comodo on Vista x64 as we speak. You need to get the 64bit version of it.
If you go here you'll see that there's a separate link for x64:

Thank you, but that seems to be a dead link. Do you have another?

 

Thank you. I'll check it out.
