If you're facing error code 0-1021 during your Office 2019 installation, it indicates that your antivirus software is hindering the process. Follow these steps to address the issue:

1. Temporarily turn off your antivirus software: Most antivirus programs offer a feature to disable them temporarily. Try this and then retry the Office 2019 installation.
2. Add Office 2019 to your antivirus exclusion list: If deactivating the antivirus doesn’t help, add Office 2019 to the exclusion list of your antivirus software. This allows the installation to proceed without interference.
3. Reinstall your antivirus software: If the previous steps fail, you might need to uninstall your antivirus program and reinstall it after completing the Office 2019 installation.
