Do not be so quick to tell me or others what the root cause is, or what does or does not pertain to this specific issue.
Nobody at Comodo has come forth publicizing the exact root cause.. so unless you actually know exactly what the root cause is I would not be dismissive of others submitted findings on what has worked.
The only solution is going to be a complete clean install of CIS and uninstalling using the official uninstaller and double-checking to make everything is removed, including files in temp folders (%TEMP%, C:\Windows\temp,etc.)
So, can you tell me how many clean uninstalls do I actually need to do?
I've already used the official uninstaller twice, double-checking to make sure everything is removed, including files in temp folders (%TEMP%, C:\Windows\temp,etc.), manual registry removal along with Revo Pro forced hunter leftover scans. There is something else going on here. Despite requested cis reports and detailed log submissions that have been uploaded to the Dev team, no one knows what the root cause is. I have been a member of the Comodo community and an even longer time user of CIS to have gathered a detailed understanding of how this software behaves and functions to know exactly how to perform either a product update to a new version (which I RARELY do as it can cause problems), or to perform a complete clean uninstall of it along with executing Comodo's official uninstaller and/or using Comodo uninstaller scripts and manual removal of any leftovers in preparation for new clean installs. I have done this for years with very successful results.
In any event, I am not satisfied or believe that a 3rd complete uninstall is needed or even required.
So at this point in time, I am done and completely ready to move away from this software.
Maybe I'll check back in a year or so and see how CIS is doing if my alternative solution is no longer favorable.
