Not recognizing firewall?!

I’m using free version of comodo firewall, and I downloaded SystemCheckup from Iolo, and when I run the test, it said that I had no firewall protection and some serious security problems. Why is that?
I am familiar with System Mechanic 5, and have no complaints about that program, and I’m considering buying “new” version 6, but why doesn’t it recognize Comodo firewall?
