Win7 x64 and CIS 3.13 firewall

Does CIS 3.13 firewall have a full (and native) support for x64 Windows 7? Or should I wait for releasing CIS4 for full Win7 support?

Do I have to disable Windows own firewall when using CIS firewall? I would like to use both firewalls at same time if there is no conflict between them.

AFAIK there is a support for Win7 x64. I use it myself in this combination and never had any problem.

It’s not recommend to run two/more firewalls at the same time. It could come to conflicts between them and also BSOD.
And if you have CIS firewall, you don’t need Win FIrewall.
