To install MS Office on your Mac running macOS 13.7.8, you can follow these steps:

1. Check Compatibility: Microsoft supports only the three most recent versions of macOS. Since you are on an older version, you may need to install an older version of Office that is compatible with macOS 13.7.8.
2. Download Older Version: You can install version 16.100 of Office for Mac, which should work on your system. Look for the installer that corresponds to this version.
3. Activation: After installing, you will need to activate Office using your existing Office license.
4. Troubleshooting: If you encounter issues with the installation or activation, consider using the Microsoft 365 Uninstall troubleshooter to remove any previous installations before attempting to reinstall.

By following these steps, you should be able to reinstall MS Office on your Mac successfully.
