Revo Uninstaller Update

Hi, hope tis is the right forum. I’ve recently started to use COMODO firewall but can no longer update my Revo Uninstaller product - it says firewall has blocked the update. How do I allow this please?

Open CIS>Firwall>Advanced>Network Security Policy

See if there is any entry for Revo… Either Remove the entry and apply it and try Revo updater again… This will give a pop up … Allow it (with or without remember) and it is done

Or just double click the application rule and change it to a predefined policy… like trusted application.
