Transition from version 11 on version 12

Hello. I wish to learn as it is possible to pass from version 11 Comodo Internet Security to version 12 ?

I have downloaded the offline installer for v.12 and run it while v.11 was already installed on my PC.
It asked me to reboot to complete the setup, I got an error message about cistray not being able to start, then the installation process went on.
After rebooting once more, v.12 was installed and fully functional without any issue.

If you don’t dare to try this, you can download the official comodo uninstaller and run it to uninstall v.11, then install v.12. Just remember to export your configuration before uninstalling v.11
