Uninstalling CFP for Vista 64

During the automatic update of CFP, it showed a pop-up displaying:
Error while loading resources from C:\Program Files\Comodo\Firewall\cfpconfg.dll. Aborting Application.
From that moment on, it has been impossible uninstalling or upgrading CFP, it always displays that message.
Btw, I couldn’t find cfpconfg.dll on my pc, neither on other machines where CFP is installed.

Anybody can help?
Many thanks.

Exactly the same problem after automatic update. I have XP 32.

Same problem with me!!! Someone help please!!! Mine is Vista 32
