Launchpad was sort of like a security centre from where all of the Comodo applications could be launched etc.
As of version 2.3 Launchpad was removed from CFP and was no longer included in the download of the firewall. As of version 2 of the antivirus this is also the case.
Comodo will eventually phase out launchpad from all their products, but it may be available as an optional download in the future.
Launchpad was phased out as the vast majority seemed to want it removed. Something similar/better may be available in future.
