This is a problem of Xp and not of the Comodo Firewall.
For resolving it:
1. At the command line of windows XP "Start" ->"Run" enter the command "CMD.EXE" and press Enter.
2. At the new window (Command Prompt window), type "NET STOP WINMGMT /Y" and press Enter. Then type "exit" end press Enter again.
3. Then go at the folder C:\windows\system32\wbem and delete the folder "Repository".
4. Reboot windows. The folder will be recreated by the Security Center and will display the correct information.
I did as adviced here, but it didn't work.
I still can't reinstall Comodo. I still get this message:
"you seem to be having Comodo firewall installed using older version of installer. Please go to 'start....'and un-install Comodo firewall."
Maybe i can tell you a little bit first why i want to reinstall?
Actually it was not my intention to uninstall Comodo. I had it on my laptop for a while (and still), and as i am quite satisfied by this firewall, i wanted to install it on my PC as well.
However, i guess i made a mistake by not installing it on the same partition as where my operating system is situated. The firewall didn't want to start up.
So, i decided to uninstall it and then reinstall it on the proper partition. Well, that didn't work, i got that message of 'older versin...and so on'.
Then i decided to remove any file that was still on my system, and to remove any registry key still present. So i did, however there is one reg key i can't seem to remove (why?):
(deviceDesc REG_SZ Comodo application Agent)
Maybe this is causing the trouble of reinstall?
I also tried as suggested above, but that din't work as well.
I don't know what i could do next. Could you help me out? Thanks.
