The older versions of Office installer have a certificate within them to make sure they are not tampered with. This certificate has an expiration date which on the 2011 version has expired. I would recommend you get a newer version that works on your given OS-X/macOS or you’ll need to alter your systems date back to 2012/13 so the installer thinks its back within the certificates window.

I would also make sure you are running the highest version of OS-X/macOS your system supports as well to be safe.

For reference: If you've got an old macOS install image, it will probably stop working today
