How do I unblock programs?

When I goto SETTINGS/HIPS/MANAGE, a list of things blocked will start to display then the entire window disappears. CAVS is still running, but the program window closes. This happens on 3 PC’s I installed on yesterday. Only workaround I could find was to uninstall to unblock programs

Open Comodo Antivirus. Go to settings on the tabs at the top. In the lower middle of the screen you should see:

“What items to exclude from HIPS Application Control.”

Click on “Select” not “Manage” and browse to the application and select it and apply.
