Installed latest Comodo. It installs and runs, but does not turn on firewall (big X). Click on run diagnostics, let it try to fix problem, but still no go. Shut off Windows Firewall (I had put my modem on standby!) but no difference. It appears it can't find a few files its looking for.Anyone get it to work?tia!!!

I tried that and got an x05 (access) error.see this thread http://social.technet.microsoft.com/Forums/en-US/w7itprogeneral/thread/1d4fe168-999c-49fa-b6ac-f565f6e3a765so I reverted to the 9th, reinstalled Nvidia, but with Vista Compatibility, and then installing Comodo wth Vista compatibility worked perfectly.
