I haven’t been able to successfully update CIS in the past three versions. First time, the network firewall driver didn’t load - uninstall and reinstall - worked. Second update, same thing happened. Latest update, Vista UAC prompt became delayed and certain programs became “unrecognized” where the Vista prompt turns yellow for a file without a signature- again uninstall and reinstall fixed it…
and now Comodo says I need an update even though I have the latest version (I think this is a known bug).
