What does Installation Mode do?

I’m installing various software, and set the firewall to Installation Mode, but there’s still hundreds of popups.

Firewall is set to Safe, and Defense is set to Clean.

Also, how do you set the timer for when the firewall asks if you like to go back to the previous mode.

You should not received more than two.
First Alert Explorer.exe execute ?? (Installer)
When you receive the next alert choose Installer or Updater screenshot.
Then CIS popup do you want to switch to installer mode click yes.
You should not have anymore alerts after this.

  1. What does Installation Mode do?

  2. Does it affect anything if you activate Installation Mode during the install process of one of the software?

  3. “choose Installer or Updater” - is this permanent? or just for that install.

  4. How do you set the timer for when the firewall asks if you like to go back to the previous mode?

  1. Quote from help file CIS.
    ‘Installation Mode: Installer applications and updaters may need to execute other processes in order to run effectively. These are called ‘Child Processes’. In ‘Paranoid’, Safe Mode’ and ‘Clean PC modes’, Defense+ would raise an alert every time these child processes attempted to execute because they have no access rights. Whilst in one of these 3 modes, Comodo Internet Security will make it easy to install new applications that you trust by offering you the opportunity to temporarily engage ‘Installation Mode’ - which will temporarily bestow these child processes with the same access rights as the parent process - so allowing the installation to proceed without the usual alerts.

  2. Installation Mode only works if you choose a application as Installer or Updater.
    If you select another application as Installer or Updater whilst still in Installation Mode this application as the same rights as 1)

  3. If you do the same as the alert in the screenshot and do not tick the box Remember my answer it is just for that install.

  4. Sorry you cannot set the timer it is preset by Comodo not sure I think about 4/5 minutes then you receive a popup do you want to stay in Installation Mode.
    Just leave if you have not finished installing (the alert disappears after approx 10 secs) it stays in Installation Mode.

I have been trying for the longest time to figure out what Installation mode is, why I continue being harassed by intermittent “installation mode/previous mode” reminders with maddening frequency that are extraordinarily annoying, distract to the point where I have disabled COMODO in its entirety to stop it.

Can no one describe to me in simple, layman’s terms what Installation Mode is and why despite assurances that it shouldn’t appear more than only a few times, I continue being subjected to it, tormented by it, is
what it really is more akin to, untold number of times I use my computer???

The last attempt at installing Comodo nearly a year ago had me uninstall it for this very same reason and am
going to have to give up on using your otherwise exemplary desktop application if I am unable to figure out
how to resolve the issue.

Any assistance on this matter is greatly appreciated.


Are you saying that you get the reminders after you have returned to previous mode?

Installation mode suppresses the popups that would normally be associated with an installer wanting to do numerous processes. Access/change registry keys, interface with explorer or COM, etc…

So instead of bombarding the user with popups on an install, CIS quietly lets the installer do it’s work.

Then when it is finished, it reminds you that you are in installation mode and asks if you want to turn it off. (The answer is likely Yes)


Starting with the assumption that you have installed CIS and your PC is on and ready at the desktop;

  1. Put shiny new CD in drive to install shiny new software application
  2. When the installer starts (either automatically or manually), you should receive an alert that XYZ.EXE is trying to do something (this alert releates to the installer software we just started)
  3. Since we know this alert is related to the software we just intentionally started, in the alert window, we should select “Treat this as” and choose “Installer or Updater”. This will put the firewall/D+ into Installation mode. When in Installation Mode, CIS monitors the application that was nominated as an Installer or an Updater (in our example XYZ.EXE). It allows that application, and other applications that are started by that application (XYZ.EXE), to do it’s stuff, unhindered by alerts from CIS. CIS is still monitoring other applications and providing pop-ups for them. It’s just XYZ.EXE (and any sub-ordinate apps that XYZ.EXE started during the install) that is treated as being in install mode.
    4a. If the installation completes in under 5 minutes, you can wait till 5 minutes (from the commencement of the installation) has past and then you should get an alert asking if you want to stop using Installation Mode. As we have completed our installation, we would naturally answer YES, as which point CIS will revert to whatever mode it was in before we chose to start Installation Mode.
    4b. If the installation finishes in under 5 minutes and you don’t want to wait for the “Do you want to stop” alert to appear, you can open CIS and click the “Switch to previous mode” link in the right hand side of the CIS window.
    4c. If the installation takes more than 5 minutes, at the 5 minute mark you will receive an alert asking if you want to switch back to the previous mode. As the installation is still proceeding, you should answer “No” and allow the installer to continue. From this point onwards, you will receive regular alerts asking if you want to switch to the previous mode. What CIS is really asking is “Is the installer finished yet?”. If it isn’t, answer “no”. If it has finished by then, click “Yes”.
  4. Once you have answered “Yes” to indicate you are finished using Installation Mode, CIS will revert back to whatever mode it was in before we started the installer in step 3.

In a nutshell;
Install software
Select Installation Mode
When prompted, answer “No” until the installer is finished
When prompted, answer “Yes” if the installer has finished
Installation Mode alerts should stop.

If you are getting repeated installer alerts, it’s because you chose to start installer mode and haven’t yet told CIS that the installer has finished.

Hope this helps,

“Installation Mode only works if you choose a application as Installer or Updater.”

Oh, though I had changed Defense+ to training mode.

I’m comfortable using my desktop now.

Do you mean you have Defence+ in Training Mode permanently?
Please do not.
Training Mode should be only used for very short periods like running a game for the first time to learn rules needed for the game to run in full screen where you cannot see the alerts.

Training Mode allows all so if you placed Defence+ permanently in Training Mode it is effectively disabled.

So the difference between Disabled and Training Mode is that Training Mode learns and Disabled does not.

Your reasoning doesn’t make any sense because most people don’t know how to use these types of programs and click ‘allow’. 99.9% of the ‘allows’ are appropriate; plus my applications doesn’t do any funny business (that I or the firewall knows of).

Do you have any real reason for setting higher than Training Mode??

Ummm… Absolutely!

I’m not sure why you can’t see that continually running D+ in training mode isn’t a good idea. You’re basically telling D+ to learn the processes of anything new on your system. So if malware gets introduced, instead of blocking the behavior, your setup will learn and allow those processes! You’re basically giving any malware free reign on your system.

If anything, run it in training mode for a day or so to learn your applications, (only if you’re sure your system is clean) and then switch to safe mode. Leaving D+ in training mode is only asking for trouble.

“So if malware gets introduced…” - well i guess i’m not expecting malware or any other evilwares to be introduced.

“run it in training mode for a day” - i’ve been running it for much more than a day, and it’s perfect.

“only asking for trouble.” - from experience, i’ve to say i sincerely disagree; in fact, setting it higher than training mode is what immediately demands troubles.

what you people in general should do is create excessive viruses and other evilwares so a rarity of people like me who are more sensible have increased reason to panic and live in an unlivable, fearful world.

Keep on keeping on my friend… 88)

maybe clearer english would make this ‘intelligent discourse’ more interesting…

I meant that it’s obvious that nothing anyone can say will change your mind, so continue doing what you are doing.

I just don’t see the point of running a firewall and an HIPS such as D+ if you going to give them both blanket ‘allow’ rulesets. You’re rendering your security applications useless, so you may as well just uninstall them.
