Antivirus will not install

When installing internet security, Error occurs during installation, When i restart computer, diagnostics fixes installation. Restart again, Firewall and Defense+ becomes active. Antivirus is not availbile. When I try to add antivirus… Error keeps occurring.
Product version is 3.13.126709.581

What error is occurring during installation. Is it the same error when you try to add the AV?
