- ben thank you i can’t stand any other internet security programs and was almost about to give up. great help thank you
- Miri Thanks it worked! (Too bad I got that license key before reading your advice…)
- Myself No it doesn’t works. Same error after retry, error occurs while kernel drivers install. Tracy Which version of Comodo is it that you are trying to uninstall? Have you tried using a uninstaller like Revo Uninstaller? Have you tried in safe mode? Have you run the clean up tool as a administrator?
- Perio2010 It worked for me!!
- A guy out his mind because fxxing COMODO 4 not work at all
- Oompa Loompa I was skeptical… but thank you … your tool and tips removed my roadblock of the error 1603 when installing…. Thanks again
- John Mihaljevic Have run the CIS Clean-up Toolas per your instructions, but CIS still fails to install. I have Windows XP Home SP 3.
- Terry Thank you very much for this fix. It’s greatly appreciated
- Rakulus Thank you!!! Had old Comodo Firewall and Avast antivirus and was trying to update. This fixed the install error!
- fatima worked perfectly, thanks.
- jpvenail Thank’s your bat file really works
- Tracy Updated the batch script accordingly.
- Anonymous The following lines in the batch script have typos: REG DELETE “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\ CurrentVersion\Explorer\Browser Help Objects\{F0D4B231-DA4B-4daf-81E4-DFEE4931A4AA}” /F REG DELETE “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\ CurrentVersion\Explorer\Browser Help Objects\{201f27d4-3704-41d6-89c1-aa35e39143ed}” /F They should read “Browser Helper Objects” on Windows XP.
- Davie Many thanks for this, I was getting the Error 1603 until running the clean-up tool. Installed no problem after use!
- TedS Worked fine on my Vista system. Thanks
- A guy out his mind because fxxing COMODO 4 i think i still can’t install COMODO 4 forever fxxking 1603 error appear again and again even using this CIS Clean-up Tool WTF COMODO you want to tell me i need FORMAT MY HARD DRIVE?! I would rather use COMODO 3 than use COMODO 4
- effectus saved my day. thanks so much!
- Simon Works. Thanks!
- Richard Thanks for publishing this. It doesn’t say much for Comodo that this has been a problem since March and they haven’t fixed it yet. What about the non-techies out there that won’t have a clue about finding a solution.
- Dave Great Script, worked a treat, many thanks!
- Steve Thanks very much. This was causing me mucho stress. I really appreciate it.
- Tracy @Fernando Assis There has been a few issues with uninstalling Comodo products and this has put people off. I can only assume that Comodo know about this and are surely addressing the issues.
