Chosen Solution
Hi, I was wondering if you could help, everytime i open Word, Powerpoint, or excel for mac (the rest work fine), It comes up with “The Office for mac installation did not complete successfully because there was a problem with the installer”
The problem is solved, I downloaded a fresh copy of office
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
