Kerio Personal Firewall

Hi there.

I have been using KPF since last year and recentrly after having
installed a fresh sytem: XP Pro SP2 I have also install KPF 2.2.x (I
don't remember :/). I found one problem with KPF which it wasn't
before. I can't install programs untill KPF is switched off :/. I don't
know what I have been done wrong but I can't do it. If anyone knows how
to resolve thos problem please help me. I tried to change the
application behaviour rules but it doesn't help.

Regards.
