Dear @Frank
Thank you for posting your question in the Microsoft Q&A forum. After reviewing them, we have integrated these excellent points into a more comprehensive action plan to resolve the installation issue.
The problem you are facing strongly points to deep-seated conflicts from the pre-installed Office versions, combined with potential interference from system settings or other software. Since the automated uninstall tool failed, a more thorough, step-by-step approach is required.
To help me narrow down the cause, could you please provide the following details?
- Have you checked the task manager to see if there’s any background process related to the Office installation that might be hanging?
- Are you using any other Microsoft Office applications or versions on the same machine?
- Have you encountered any errors in the Windows Event Viewer related to the installation process?
In the meantime, please try the following official troubleshooting steps which usually resolve issues with basic issues:
Step 1: Completely Uninstall Existing Office Versions
Since the Support and Recovery Tool encountered an error, let’s use Download Enterprise Version of Microsoft Support and Recovery Assistant from Official Microsoft Dow…tool specifically designed to troubleshoot Office installation issues.
- Download and run the SaRA Office Uninstall scenario from this Microsoft article.
- Follow the on-screen prompts to remove all Office products, including pre-installed OneNote and Microsoft 365.
Step 2: Prepare Your System for a Clean Installation
After the manual uninstall is complete, prepare your computer to ensure a smooth installation.
A. Run Windows Update: Ensure your Windows 11 is completely up to date. Go to Settings > Windows Update and install all available updates. A fully patched system can prevent many common installation errors.
B. Clear Temporary Files: Leftover installation files can cause conflicts.
- Press the Windows Key + R to open the Run dialog.
- Type %temp% and press Enter.
- Select all files and folders in this directory (Ctrl + A) and delete them. Skip any files that are currently in use.

C. Temporarily Disable Security Software: Your antivirus or firewall software could be blocking the installation. Temporarily disable your third-party antivirus and firewall programs just before you begin the installation process. Remember to re-enable them immediately afterward.
Step 3: Reboot and Re-attempt Installation
Once you have completed all the cleanup and preparation steps above, reboot your computer. This is essential to finalize the changes.
After restarting:
- Right-click the Command Prompt icon and select Run as administrator to open an elevated session.
- Navigate to the folder containing your Office Deployment Tool files (
setup.exe and customconfig.xml).
- Execute the installation command:
setup.exe /configure customconfig.xml
