Locate Microsoft Office

Scroll through the list of installed applications until you find your Microsoft Office installation.

Modify the Installation

Choose Online Repair

Select 'Online Repair' from the dialogue box and click 'Repair'. Wait for the process to complete, then restart your computer.

Quick Repair Alternative: If you are currently without an internet connection, you can try the 'Quick Repair' option first. It runs faster and relies on locally cached files.
