Microsoft Office error code 30015‑11 typically occurs during Office installation and indicates a failure in reading or writing installation files—often due to corrupted data or permission restrictions. Here’s how to resolve it:
- Re-download the installer
A damaged setup file may be the culprit. Download a fresh copy of the Office installer from your copyright. - Run as administrator
Right-click the installer and choose Run as administrator to ensure it has full access to install files. - Temporarily disable antivirus/firewall
Security software can block file operations. Turn off your antivirus or firewall, run the installer, and then re-enable protection. - Repair system files
Open Command Prompt as an administrator and run:
sfc /scannow
This will detect and fix corrupt Windows files that might interfere with installation.
- Uninstall and reinstall Office
Use Control Panel or Microsoft's uninstall tool to remove Office completely. Restart your PC and reinstall Office using your fresh installer.
