CPF module can't be activated after installing CAV

Yesterday I have downloaded both Comodo Firewall and AntiVirus. I have removed my old firewall and antivirusapplication (after disconnecting from the internet :slight_smile: ) Then I installed the Firewall. It seemed to work ok. After this I have installed AntiVirus. From the moment I have installed Antivirus the Firewall modules can’t be activated any more. The program itself recommends a re-install. I had no time to do so at that moment, will do so tonight, but this seems very strange to me. Is there a bug in the Install of the Antivirus? Does anyone know what might be wrong now?
