if you download directly from the website you will get Comodo Dragon v45.9.12.393 – 51mb
if you download from the forum you get version v77.0.3865.120 – 91mb
the version available on the website doesn’t update beyond a certain point due to some file not being properly signed
you should make the latest version available on the site
Further update is not possible because in the Help → About page after downloading the installation package the message “Downloaded file is not properly signed” is shown.
