Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello Thompson Eva,
To help isolate the issue, please perform the following troubleshooting steps and let me know the results afterward.
Step 1: Completely uninstall Microsoft 365/Office
Close all Office apps (Word, Excel, Outlook, Teams, OneDrive).
Run the uninstall troubleshooter from Microsoft Support, it opens the Windows Get Help app and walks you through removal.
After the uninstall process is completed, please restart the computer.
Step 2: Temporarily disable Windows Firewall
Windows Defender Firewall or third-party antivirus software may occasionally block certain installation or provisioning processes that require elevated permissions.
Please temporarily turn off Windows Defender Firewall by following these steps:
- Press the Windows key to open the Start menu.
- Type "Windows Defender Firewall" and open it.
- Click "Turn Windows Defender Firewall" on or off from the left pane.
- Select Turn off Windows Defender Firewall (not recommended) for both: Private network settings and Public network settings
Additionally, if any third-party antivirus or security software is installed, please temporarily disable it as well.
After that, please perform a fresh Office installation by following the instructions in this article: Download, install, or reinstall Microsoft 365 or Office 2024 on a PC or Mac | Microsoft Support
Once the installation is complete, please remember to re-enable Windows Defender Firewall and any antivirus software to ensure your device remains protected.
I look forward to your update.
