Office installation may fail with error code 1713 when the installer can't overwrite or remove a file—usually due to permission issues, corrupted installer files, or leftovers from a previous Office version blocking setup. This halts installation and leaves Office unusable. To resolve it, start by restarting your PC to clear temporary lockups and run the installer as an administrator to bypass permission restrictions. If the error continues, use the Microsoft Support and Recovery Assistant to fully remove any existing Office installations. Then delete leftover folders in
C:Program FilesMicrosoft Office (or Program Files (x86)), and clean temporary files using Disk Cleanup. Next, open an elevated Command Prompt and run sfc /scannow to repair corrupted system files that might be blocking installation. Once finished, reboot your PC and launch the Office installer again—preferably in a clean‑boot environment to prevent third‑party interference. If the issue persists, follow the full step-by-step walkthrough here: this guide.
