I am very satisfied with Comodo Internet Security 3.X but when I was prompted for an upgrade; my system is unable to upgrade my Comodo 3.X. to latest version. The following error incurs "Comodo firewall setup wizard ended prematurely because of an error. Your system has not been modified. To install this program at a later time, run set up wizard again" and a popup error "Cannot install COMODO firewall Error: 1603. Fatal error during installation. Would you like to try again? YES or NO" Do you have any suggestions? I am running Windows XP Professional SP3.
Unable to Upgrade Comodo 3.x
You will need to check your computer and make sure that firewall protection has been enabled, because without firewall protection the Comodo update may refuse to install. If there are any changes that you made to the system that might have caused it to have the firewall disabled then you will need to do a System Restore to remove the changes that you might have made to the system.
After that you have done the above, you will need to reboot the system and then try updating the Comodo Firewall again, and see if it will be successful. One other thing that you will need to check that may be causing the upgrade to fail is the internet connection status. You will need to make sure that you have a strong internet connection.
