This installation package could not be opened

I’m continuing to get this message after I have downloaded current Libreoffice file, when I go to run the file. This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package.

Where you have download the file?. Is the official site: https://www.libreoffice.org/download/
