sunnystaines, tried to instal again, no joy, same error when said 'yes' to uninstall old copy. According to 'Security Center', Comodo is still running, but icon gone from bottom right shortcut bar. Most perplexing!!
I created a new restore point, then restored to earlier time of yestrday, then uninstalled Comodo, then unrestored back to the present, and Comodo is still there! Dont know what to do next, cannot seem to get rid of it.
Restore to the time you were able to uninstall Comodo. Uninstall it. Don't 'unrestore' as defeats the object. If SP3 not installed at the restore point then reinstall it and use XP firewall for now. Install Comodo firewall or if lost faith in it then install another one.
