- Product
- Microsoft 365
- Device & OS
- Windows 10
- Scenario
- Installing Microsoft 365 after performing a fresh installation of Windows 10.
- Observed behavior
- The installation stops at 95% and fails with errors 30015-11 and 2031. Removing Office and running Microsoft diagnostic tools do not resolve the issue.
Ensure your computer is plugged into a reliable power source and connected to a stable internet network to prevent any interruptions during system updates.
Install Windows Updates, Drivers, and BIOS
Update your core system components to ensure your fresh Windows 10 environment is fully compatible with the Microsoft 365 installer.
A fresh Windows 10 installation often lacks critical security patches and updated drivers required for running complex application installers like Microsoft 365. Updating these components usually clears the 95% installation freeze.
Navigate to Start > Settings > Update & Security > Windows Update. Click 'Check for updates' and let the system download all pending security and system updates.
Open your web browser and visit your computer manufacturer's official support website. Locate your specific computer model and download the latest available device drivers and BIOS firmware.
A new Windows installation may require multiple restarts to fully configure downloaded updates. Restart your PC at least twice after installing the updates and BIOS.
Once all updates are applied and the system has restarted, run the Microsoft 365 installer again.

Perform a Clean Windows Installation
If standard system updates fail to fix the persistent 30015-11 and 2031 errors, reinstalling Windows 10 from a USB drive can resolve underlying corruption.
Switch to WPS Office to Bypass Installation Errors
If Microsoft 365 consistently fails to install on your Windows 10 machine due to unresolved system errors, WPS Office provides an excellent alternative. It is a powerful, lightweight suite that installs in seconds without relying on complex system dependencies.
- 1. Download the Installer: Visit the official WPS Office website and click the free download button for Windows.
- 2. Run the Setup: Double-click the downloaded setup file. The lightweight installation takes only a few moments and avoids complex registry modifications.
- 3. Open Your Documents: Launch WPS Office immediately after installation and start editing your existing Microsoft Office files without any compatibility issues.

Frequently Asked Questions
Why does the Microsoft 365 installation stop at 95%?
Installations often hang at 95% because this is the final phase where the software registers system services and configures the registry. Conflicting background processes, missing Windows updates, or outdated device drivers can block these final configuration steps.
Will the Microsoft Support and Recovery Assistant fix error 30015-11?
The Support and Recovery Assistant can fix many common Office installation issues. However, if the error stems from incomplete Windows updates or outdated motherboard BIOS after a fresh OS installation, the diagnostic tool generally cannot resolve it.
Can I install Microsoft 365 without updating my BIOS?
While it is sometimes possible, outdated BIOS firmware can cause severe compatibility issues on a fresh Windows 10 installation, triggering errors like 2031. Updating the BIOS is strongly recommended if you face persistent failure.
How do I completely remove a failed Microsoft 365 installation before trying again?
You should use the official Microsoft Office uninstall support tool. This tool completely scrubs remnants of the failed installation from your registry and program files, ensuring a clean slate for your next installation attempt.
