No problem 
Any suggestions for my issues of âadministrative privilegesâ ??
With the current version 2.3 I believe you must be an admin to activate, otherwise it will not let you, however it is possible that in future versions you will be able to activate without being an admin.
Melih, it is not that easy. I have Comodo Firewall downloaded, but I canât install the activation key. When I click to activate it, I get a window that says it canât find the page. I tried to download the verification engine also, and got the same page

It sounds as if, there is an entry for Comodo in your host file.
pls remove it and then try again.
thanks
Melih
Melih, I donât mean to sound ignorant, but what host file, where?
Melih, I found the Hosts files, I found the secure.comodo.net entry, but I canât delete it or get the # symbol stay. Help!!!
Hi,
Try renaming itâŚdo what you need to doâŚthen rename it back to its original name.

often the HOSTS file is read-only
right-click, choose âpropertiesâ and un-tick the âread-onlyâ box, edit the HOSTS, save &
check the âread-onlyâ box (makes it a bit harder for â â â â -ware to insert itself in the HOSTS- file)
Gordon, That worked great. No problem with activation nowâŚThank you very much
Hi!
One noob question: Can I have unlimited number of deinstalation/instalations of CPF on the same machine, or do I have to ask for new activation key for each new installation (I hope not)?
ThanxâŚ
Hi,
Reinstalling on the same machine does not require you to re-register as the instalation will detect the previous licence - unless you did something such as reinstalling Windows.

Thank you. I suppose the certificate in the Program Files\Trustix folder has something to do with it 
I have a key but get the famous 2146697211 error when trying to activate it. (win200 sp4, have avast but tried with it disabled)
I have tried everything in the FAQs and threads:
nothing in HOSTS file,
uninstalled and reinstall CPF (latest release) from system partition,
updated windows script,
using IE6 with all updates as default browser,
reregistered the MSXML3 dllâs
⌠tried all the suggestions I can find.
any new ideas? any new versions coming out soon?
Hi,
Yes, the licence certificate is kept in that folder. If you are wondering why the folder is called Trustix, it is because there used be Trustix firewall by Comodo before CFP, so to keep backwards compatibility they had to keep the folder named as Trustix.

Hi,
I believe version 2.4 (which should be released today - 18th Jan 2007) has a different method of activation. You may try this when it is released and let us know.
Mike
Correct, version 2.4 will activate each PC it is installed on automatically, no registration code will be needed.
Ok, thanks for confirming that Justin. I wasnât 100% sure if it was this version or a later version.

hi everyone
please i need your help.
i have problem with activation and using updater:
As recommendation from computer magazine about the powerful your firewall is,i installed the firewall with no problem at all.
You sent me activation code to my email,when i tried to activate it: i received an error:
An error has occured,error-2146697208,unknown error
please contact support
Than when i tried to use updater to update the software i received another error:

error 108:could not complete update process
be sure that you are online and connected to the internet.
I am sure that i was online because i have broadband

I used to have zone alarm free firewall with no problem,uninstall zone alarm,restart pc,than install your software,than i couldnât activate it,and update it
I hope to hear from you very soon
