Since I am having trouble using the update link in Comodo, if I download the complete new version of Comodo and install it will I lose all my preferences and knowledge stored by the older version? [I note that Comodo wants to uninstall my old version (184.108.40.2066) before installing the new version]. Thanks
Go to miscellaneous/manage my configuration and export your old settings before you do the update. Then you can reimport them later. As soon as the update is finished and you have rebooted, it is also a good idea to export your new settings just in case the old ones give you problems.
