Resolving Error 25004: Incorrect Product Key Installation Issues

Error code 25004 can be addressed through several strategies:

1. Verify the product key's compatibility with your specific Microsoft Office version. Ensure it aligns with the intended version and edition.
2. Remove any existing Microsoft Office installations that might conflict with your new installation. Employ the Microsoft Office Removal Tool for a thorough uninstallation.
3. Temporarily turn off any antivirus or firewall settings while installing. Security software can occasionally disrupt the installation and lead to errors.
4. Opt for online activation of the product key rather than phone-based activation. Online methods can often circumvent common activation problems.
