I can't unistall v3 due to an error about cfpres.dll?

Every time I try to uninstall v3 I get this "ERROR: Could not load C:\Program Files\COMODO\Firewall\cfpres.dll Please check if installation folder has this file. Aborting application. I checked the folder and I don’t think it’s in there… and I can’t uninstall it by installing it again.

DO you have Comodo installed already? If so read here.
