Error code 30045‑44 often appears during Microsoft Office installation or updates and is usually caused by corrupted installation files, insufficient permissions, or interference from security software. To fix this, start by uninstalling any existing Office installations using Microsoft’s removal tool, then restart your computer. Download a fresh Office installer from your official Office portal, ensure you run the setup file as an administrator, and temporarily disable antivirus or firewall software that might block components. If issues continue, clear temporary files from the system using Disk Cleanup or manually deleting %temp% contents. Finally, run the Windows Installer refresh commands msiexec /unregister and msiexec /regserver in an elevated Command Prompt to reset the installer service.
