- Restart your computer and close any running Office-related processes from Task Manager.
- Always launch the installation using
setup.exe
from the root of the Office installation folder instead of any individual MSI file. - Uninstall any previous or partially installed versions of Office and delete residual folders from Program Files and AppData.
- Temporarily disable any third-party antivirus or firewall software to prevent interference with the setup process.
- Open Command Prompt as administrator and run
sfc /scannow
to repair any corrupted system files. - After cleanup, rerun the Office installer from the correct setup location with full administrator rights.
