How to Fix Office 2021 Installation Stuck at 97 Percent
Question details
The user is unable to complete the installation or repair of Microsoft Office 2021 because the process repeatedly freezes right before completion.
- Product
- Microsoft Office 2021
- Device & OS
- Windows
- Scenario
- Attempting to install, update, or run a standard online/offline repair for Office 2021.
- Observed behavior
- The installation or repair progress bar halts indefinitely at exactly 97 percent, and standard repair attempts do not bypass this freeze.
Make sure you have your Microsoft account credentials readily available and verify that your Windows operating system is fully updated before attempting a clean reinstallation.
Use the Microsoft Support and Recovery Assistant
Microsoft provides an automated troubleshooting tool designed specifically to diagnose and resolve stubborn Office installation and uninstallation issues.
The Support and Recovery Assistant (SaRA) is the most effective first step for installation failures. It runs automated checks to identify registry errors, conflicting background services, or corrupted setup files that cause the progress bar to hang at 97 percent.
Visit the official Microsoft Support website and download the Microsoft Support and Recovery Assistant tool.
Open the downloaded executable file to install the tool, then launch it from your desktop.
Choose 'Office' from the list of products, then select the specific problem stating you are having trouble installing or uninstalling Office.
Follow the on-screen prompts and allow the tool to apply its recommended automated fixes.
Perform a Clean Reinstall Using the Offline Installer
If automated tools fail, manually uninstalling Office and utilizing an offline installer bypasses potential network interruptions that trigger the freeze.
Tired of Installation Errors? Switch to WPS Office
If Microsoft Office 2021 continues to freeze during installation, consider switching to WPS Office. It is a powerful, free, and incredibly lightweight alternative that installs in seconds without complex setup requirements, allowing you to get back to work instantly.
- 1. Download WPS Office: Navigate to the official WPS website and click the Free Download button.
- 2. Run the Installer: Open the downloaded file. The fast-track installer will set up the entire suite in just a few clicks.
- 3. Open Your Documents: Start using Writer, Spreadsheet, or Presentation to seamlessly open and edit your existing Microsoft Office files.
Frequently Asked Questions
Why does my Office installation always get stuck at exactly 97 percent?
The 97 percent mark is typically when the Office installer attempts to finalize registry settings, register background services, and create shortcuts. Conflicts with existing software, antivirus blocking, or corrupted temporary files often cause the setup to freeze at this specific finalization step.
Will I lose my saved Word and Excel files if I completely uninstall Office?
No. Uninstalling Microsoft Office only removes the application files from your system directory. All of your personal documents, spreadsheets, and presentations saved locally or on your OneDrive remain completely untouched and safe.
How do I check if my Windows is 32-bit or 64-bit to download the correct installer?
Press the Windows key + R to open the Run dialog, type 'msinfo32', and press Enter. Look for 'System Type' in the System Summary pane to see if your computer is x64-based (64-bit) or x86-based (32-bit).
What is the difference between the standard installer and the offline installer?
The standard installer is a small file that downloads the bulk of the Office application data over the internet during the installation process. The offline installer is a large, complete package that contains all necessary files beforehand, preventing installation failures caused by slow or dropping internet connections.
