Before you do the things below look here and see if it can solve your problem;topicseen.

Did CIS installation with any errors? If not uninstall it and clean the registries with CSC (comodo system cleaner). Before you install CIS right-click on it, select properties unlock it and then go to compability and choose run as adim.

I hope this will help.

P.S If you are running Windows firewall disable it
