QUESTION: Is there a way to reinstall from files on my computer? Every time I have to reinstall the install downloads all the files again. I have no idea how to actually send the report. I ran the diagnostics as suggested and came up with the same message except that now I was invited to create a bug report. Win 7 Home Prem 64.Ī couple of days ago CIS could not start at reboot. I can’t tell you the exact version, but it’s the one I DL’d today. Thanks to Forum for easy, fast und quick help! Keep it going! :-TU :-TU :-TU :-TU

As a SW developer I can understand that not every case can be checked before. Thanks to Comodo for providing a free and good piece of software. Maybe a roleback option is also an option. I guess some people don’t have a second system to download uninstallers and do some research if the system is fu**ed after an update without any warnings/errors. My suggestion would be to add a check to the installer / updater to avoid such issues (if it’s possible). I didnt try to install KB3033929 as the last system was set up about 3 years ago and the KB is from 2015 (replaced by plenty of new ones according to MS). Installing KB4474419 and KB4490628 and a clean CIS installation afterwards solved the problem. Many thanks for fast help! CISfan, mertavunduk, C.O.M.O.D.O RT, ab52003, oldrotary :-TU :-TU :-TU :-TU Please see this thread for more info and how to get those updates: You need to have at least the Windows updates KB4474419 and KB3033929 installed to be able to install CIS V12. I use Windows 7 64-bit SP1 too (with all MS Windows updates installed) and CIS V12. Could you please install KB4474419 and KB4490628 then try it again? Thank you for your feedback and please let us know the result Thus, unsgined driver error is expected when updates are not installed. Win 7 doesn’t support some certificates without these updates. Is that all? Or is there missing more reagarding the unsigned driver error? I attached the report. I read somewhere that KB4474419 and KB449062 are requiered. System: Win 7 64bit (pretty sure not up to date as updates are turned of) Firefox and Internet now still working but CIS not running. Upon restart Agent is not able to start as well. (Internet Security Helper, Internet Security Sandbox, Internet Security Eradication Driver). During installation I got 3 Windows signed driver warnings telling me that Comodo is trying to install an unsigend driver.

Second I gave the offline installer a try. Finally got the uninstaller tool and was able to clean CIS completely. Disabling the Firewall driver in adapter settings didnt help. Unistall over Add/Remove Programs was not possible.

InternetExplorer opened but the network speed was like 1bit per second. Everything looked fine during installation.
