Comodo Database Update Failing at Install signatures

Comodo has been showing me this message for a few weeks: “The virus signature database is NOT up-to-date”

Everytime I try to run the updater the “Install signatures” process fails.

I see this when updater completes:
Task: Install signatures
Status: Interface not registered

You need to re-install and make sure what ever registry cleaning software you use doesn’t remove CIS related entries. Or you can try to run a diagnostic to see if it will fix it, but I’m think you will need to do a re-install.
