Hey marsoul
I think something similar happened to me on 7 recently and if i remeber correctly i had to delete a registry key.
Using Regedit have a look for the key Computer\HKEY_LOCAL_MACHINE\SOFTWARE\ComodoGroup
If that key is there and you haven`t got any other Comodo products on the pc try deleting it.
Matt
no it didnt help !
everytime i want to install the error message pop up to send the error message to comodo !
Have you tried running the clean up tool referenced in this topic Comodo Forum
After that do a search in the registry for Comodo and delete any keys found (there will be some legacy keys you cant delete but these shouldnt matter)
I should of written down what i did :-[
no it didnt fix the problem 
I think something similar happened to me on 7Are you running on a guest account or an administrator account??? what kind of windows??? 98, 2000, (xp home or pro) vista. also if on windows 7 what version of windows 7 like 7100 or 7129 or 7229 or 7260 or 7600 <---you get the idea also are you use 86x (32X) or 64x
i have 64bit version of windows 7 RC 7100
Here are a few extra things to look at when doing a clean install:
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”.
C:\WINDOWS\system32\drivers\cmdGuard.sys
C:\WINDOWS\system32\drivers\cmdhlp.sys
C:\WINDOWS\system32\drivers\inspect.sys
C:\WINDOWS\system32\guard32.dl
No !
I have done all the steps you said but still get the error sending report in installation process !!!
Try disabling all other security and network related programs that are running in the background.
When that doesn’t help do as follows. We are gonna take a look to see if there are some old drivers of your previously uninstalled security programs are still around. Go to Device Manager → View → show hidden devices → now look under Non Plug and Play drivers → when you see a driver that belongs to your previous security programs click right → uninstall —> reboot your computer.
When the problem persists make sure there are no auto starts from your previous security programs. Download Autoruns and run it.
This program finds about all auto starts in Windows. This tool can therefore seriously damage Windows when not handled properly. After starting go to Options and choose to hide Windows and Microsoft entries and then push F5 to refresh.
Now check all entries to see if there are references to your previous security program. When you find them untick them. After unticking reboot your computer and see what happens.
In case you want to be absolutely free of CIS left overs (forget about the Legacy keys as they are too much work):
Uninstall CIS and reboot. Then run [url=http://system-cleaner.comodo.com/]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 storeTo 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:

oo. HKEY_LOCAL_MACHINE\SYSTEM\Software\Comodo\Firewall Pro*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: https://forums.comodo.com/help_for_v3/comprehensive_instructions_for_completely_removing_comodo_firewall_pro_info-t17220.0.html;msg119226#msg119226
thnx, i just go to safe mode and reinstall comodo from there, it didnt gave me an error !
now it seems working properly !
Congrats on solving it. :-TU Glad it worked out for you.
I had the same problem, but after manually removing the installation folder and deleting references to COMODO in the registry, only then was I able to install it again.
Hope someone else finds this useful.
