Hey,
i was posting in this topic: https://forums.comodo.com/install-setup-configuration-help-cis/update-rarr-comodo-security-agent-could-not-be-started-t118739.0.html which now is marked as solved, but it is not solved. for me the update screen also freezed at 81% or something, i checked the version in info and there was already shown the new version. after waiting for a long time finally i stopped the update to get the “security agent could not be started”- error on attempting to open CIS interface. i run a diagnostic, which found some errors that could not be repaired. later i got another “security agent could not be started”- error and that time the diagnostic found no error at all! (btw how to start that diagnostic manually?)
so i rebooted the computer, then commodo was back, could be opened and the new interface was shown which i changed and after another reboot it was finally changed. the icon on the desktop however keeps reappearing after deleting it. 
is my installation now ok or corrupted? i saved those two diagnostic files.
btw i already had CIS version 10 before this update.
Still waiting for some information on these issues myself but if you want to manually launch the diagnostic. Click the (?) at the top right of the application and on the menu select > Support > Diagnostics
Same issue here. I let it try to install the update for an hour, finally shut it down. When I turned my PC on this morning I got CIS failed to start like posted in this thread
https://forums.comodo.com/bug-reports-cis/agent-could-not-load-t118769.0.html
I’m running W7 and have had CIS for years now. I’m currently trying to reinstall CIS and it’s been stuck on trying to install some dragon browser (which I don’t want) for at least 10 min. Maybe its time to go back to outpost? Comodo seems to be now installing a lot of bloatware ■■■■ with no option to opt-out.
Hi Raggansta,
Thank you for feedback. This bug is already recorded.
Fix will be done soon.
Kind Regards,

hey Prem,
thanks for your answer.
is my installation now corrupted? or safe to use?
thank you Qnxunix, i run it and it didnt find any errors.
when is “soon”?
is my installation corrupted because of this installation-bug? ???
I am running Windows 10 Home 64bit version 1607 fully patched.
I updated from CFW 8.4 to latest v10 using the internal updater. The update downloaded OK but the install stopped at 81.6%. After an hour I stopped it and restarted Windows. CFW 10 appeared to start normally and said that “All systems are active and running”. Since the update, running diagnostics usually fails but sometimes succeeds. After several Windows restarts and shutdown/startups this has not changed. Running the internal updater again says that no updates are available.
CFW also appears to have lost its settings judging by the sudden flood of alerts that I am receiving since the update.
When I attempted a “change” to Comodo Firewall in Control Panel>Programs and Features it gave me an error saying Comodo Firewall couldn’t be uninstalled. The “Modify” option for Comodo Firewall in Settings>System>Apps & Features is greyed out.
So I have now joined the ever increasing number of users hit by Comodo’s unreliable updates. CFW appears to be working but it is obviously not 100% which is not a comforting scenario. I may be able to fix it with a clean install (when the offline installer is available) but first I have to rely on the unsupported CIS removal tool which doesn’t always work according to other posts on this forum.
Comodo claims that CIS is user-friendly and suitable for ordinary users. This will NEVER be true until Comodo gets their act together and makes updates reliable, streamlined and basically invisible to users who don’t have the time or expertise to fix problems like this.
i sign the previous post.
Please try uninstalling and using the removal tool based on what OS you are running from here and install again using the standalone installer. The problem stems from updating using the internal updates instead of doing a clean install.
the internal updater should work 100%… whats the use of releasing something that doesent work? i don’t feel like to again make a so called clean install just because some broken updates are released to the public… and then find the same bugs again.
Updated to Premium 10 CIS, have rebooted 4 times to get it to work. I am running Windows 7 Ultimate with all the MS updates, removed the old CIS version and Malwarebytes to install. It says it can’t install Geek Buddy, something is corrupted, then it goes on and says it installs CIS premium 10. I could get the settings to work but nothing else. I went to the original look (green) and now CIS stops working. I have started a diagnostics file, so where do I send it?
i know that page. it is very confusing and outdated. where do i get the correct removal tool for win 8.1 64 bit and where do i get the latest standalone installer for CIS please?
For Windows 8/8.1/10 use this tool and when you run it, use run as administrator context-menu. Once it is done reboot then install using the standalone install which can be found in the release topic.
