Solution 1Recommended

Temporarily Disable Network Security and VPN

Firewalls, VPNs, and antivirus software can block the Assistant from downloading required Office installation files, causing it to freeze.

Network security tools often monitor background downloads and may falsely flag or block the connection to Microsoft's servers. Disabling them temporarily allows the download to complete.

1
Turn Off Active VPN Connections

Navigate to Settings > Network & Internet > VPN. Select your active VPN connection and click 'Disconnect'.

2
Pause Antivirus Protection

Open Windows Security or your third-party antivirus software, go to Virus & threat protection settings, and temporarily toggle off 'Real-time protection'.

3
Disable Windows Defender Firewall

Search for 'Windows Defender Firewall' in the Start menu, click 'Turn Windows Defender Firewall on or off' on the left panel, and temporarily select 'Turn off' for both private and public networks.

4
Restart the Assistant

Close the stuck Support and Recovery Assistant, relaunch it, and attempt the process again to see if it progresses past 11%.

Temporarily Disable Network Security and VPN
Security Reminder: Remember to re-enable your firewall and real-time antivirus protection immediately after the Office installation or repair is successful.

Frequently Asked Questions

Why does Microsoft Office installation get stuck at a specific percentage?

Installation progress usually stops when the setup engine cannot download necessary background files. This is often caused by unstable network connections, VPNs, restrictive firewalls, or temporary server outages on Microsoft's end.

Is it safe to close the Support and Recovery Assistant if it freezes?

Yes. If the progress bar has not advanced for over an hour, you can safely close the application. Sometimes you may need to end the task via the Task Manager before restarting your computer and trying again.

Can a slow internet connection cause the installation to hang?

Yes, Microsoft 365 requires downloading gigabytes of data during installation. A highly fluctuating or slow internet connection can cause the Support and Recovery Assistant to time out and stall indefinitely.

What is the Office Deployment Tool?

The Office Deployment Tool (ODT) is a command-line tool used primarily by IT administrators to download and deploy Microsoft Office to client computers. It serves as a reliable workaround when standard user installation methods fail.
