Comodo Firewall 5 How to remove

I installed Comodo Firewall this morning & some of my apps result in “Pipe state is invalid”, and I’ve been unable to define trusted apps. As I attempt to remove the firewall with the Comodo “Add Remove Components” or thru Control Panel, I’m notified that I need Administrator auth. My Vista acct is defined as an Administrator. How do I remove Comodo firewall 5?
Thank you.

Can you uninstall it using the Add/Remove components shortcut in the start menu?

Otherwise use this clean up tool in safe mode.
