Use the Microsoft Uninstall Tool and Offline Installer
Running the official Support and Recovery Assistant (SaRA) ensures all corrupted registry keys and leftover files are removed, paving the way for a clean offline installation.

Visit the official Microsoft Support website and download the Microsoft Office Uninstall Support Tool (SetupProd_OffScrub.exe).
Launch the downloaded tool, select your specific Office version (e.g., Office 2021), and follow the on-screen prompts to completely remove all Office remnants.
Once the tool finishes processing, restart your Windows 11 computer to ensure all pending file deletions and registry changes are applied.
Sign in to your Microsoft account portal, navigate to your Services & Subscriptions, choose your Office product, and select the 'Offline installer' option from the download settings.
Mount the downloaded image file (.img or .iso) by double-clicking it, then run the Setup.exe file from the virtual drive to install Office 2021 without requiring an active internet connection.
Manually Remove Office Remnants
