Read through this topic and slept on things and thought and thought.
Attempted this AM a reinstall of V3 and still to no avail.
This time, however I had made/ set a system restore to get back to where I was at a closer time frame in case of a problem and sure enough!-- Still a problem in installation so I will opt to wait out the bug.
Too confusing for me even to try and find the above listed (un-check the protected registry key as i could not figure out what or where that is) adjustment since this install did not even get to that point, as my system merely froze up during installation, that is zero CPU usage of V3 and my system just stayed and seemed frozen. I halted the process, actually clicked 'end process' and reboot restoring to my previous working state of computer.
do hope you find the bug and make the fix. please ask for any info as i wish to assist if at all possible.
am a grateful user of Comodo, but this 'upgrade' causes me concern.
cordially,
Robert
