Windows7 installation

It would appear the latest version of Comodo does not work with Windows7 (I’ve been running the public beta for a couple of months now).

I’ve tried putting Comodo into compatibility mode (XP) but still: no go. It just won’t work. Installs fine, but won’t initialize.

Any suggestions?

Welcome. :slight_smile:

You said the latest version of COMODO doesn’t work with W7? So the previous version(s) did?
Try installing in Vista compatibility mode.

(BTW, CIS is not guaranteed to work on the windows7 beta. and there will probably not be a certified version for Windows 7 until Windows 7 is publicly released.)

Had to install in vista compatibility mode, but works fine otherwise here on Win 7 b1

Try installing like this: - YouTube

I agree,

it worked pretty good on W7 beta by installing in Vista compatibility mode…BUT
how about Windows 7 RC1?
I was totally unable to get it running !!! I mean I did, but after a couple of seconds I got a blue screen. After uninstalling, Windows was running without any shutdowns or blue screens…

It seems like I need to look for another firewall … too sad I finally found comodo after sygate PFW was not working on Vista…

In case anyone has a brilliant idea I am more than open to try it.


Try using the RC2 version from here:

COMODO Internet Security 3.9.75615.498 RC2 Released

Installs and works fine.

Does it install fine without the compat. mode on?

I didn’t use compatibility mode to aid installation of CIS and everything is working fine here.

Thanks. I just installed Win7 (yeah, I’m late doing it 88)). Dual-booting! :-TU

Arrgh - I need the Windows 7 version and the beta looks like it is closed :frowning:

Sigh - will have to revert to Win7 firewall for now … unless someone can help ?


The thread was closed because the 3.9 release has gone public.

Get the new v3.9 here: .

seems to work fine, except antivirus. It says “Antivirus-Komponente ist nicht bereit!”, which means antivirus component is not ready.
I don’t find relevant eventlog entries or anything else.

I’m using Windows 7 RC1 Build 7100 de x64 & Comodo 3.9.95478.509
Diagnose can’t fix that problem, log attached

Didi you do a clean install or an upgrade?

I just installed Win 7 RC last night with a fresh install of CIS on 32 bits and that works fine. Keep us posted.

No, I tried to download the file yesterday but I have had connection problems. Therefore I have installed an older version (3.8.65951.477 x64) but that goes completely wrong. Nothing has worked, uninstall wasn’t possible, too. But I was able to get the current version with the updater in the application directory. Now I’m on this point.

The last version works fine with win 7-v.7100,v.7127
Try again:)And please,don’t run it in compatibility mode!!

Yay :smiley:
A clean install (I also used the batch file in here) fixed this error. Thanks :slight_smile:

Are you willing to try a clean install using the following procedure?

Here is the drill (forget about deleting the Legacy keys in the registry; that’s a lot of work):

Start with exporting your configuration to a folder that is not part of the Comodo folder under Program Files. This way you can restore your configuration after the reinstall.

Uninstall CIS and reboot. Then run [url=]Comodo System Cleaner[/url] to get rid off registry keys.

Then delete the Comodo folders under Program Files, Program Files\Common Files, C:\Documents and Settings\All Users\Application Data\ .
For Vista/Win7
Users%username%\appdata\local, Users%username%\appdata\roaming\ and \Users%username%\appdata\local\virtual store

To be even more thorough open Device Manager and set it to show hidden devices under menu option View. Then see if there are Comodo driver(s) left in non Plug and Play drivers. If so select the driver → click right → uninstall and reboot.

Now delete the following:
C:\boot.ini.comodofirewall (this file may not exist).
WARNING: Do not mistakenly remove the original “boot.ini”.

*Note: It may not be possible to remove these “LEGACY” keys. If you cannot delete them, leave them in the registry. However, I have subsequently found that you MAY be able to remove these keys in Safe Mode by using a third-party registry tool. To permanently remove them may also require modifying the Permissions for each key. See:;msg119226#msg119226

Now you should be good to go

I don’t know exactly but for me you are a bit to late :slight_smile:
See the post before yours. Anything works :wink:

Hi, I am new to Win7 and Comodo (paid for other net security but not working) and it is always a worry trying out new software, especially when FREE! I feel like many others, if it is so good then why don’t people pay? I am a online bargain freak and to be honest I fear the hackers. Can anyone put my mind at rest? Oh and I have had to run another AV because I get that Win7 didn’t have one and would I like to find 1 online. I installed twice and not in compat mode.
