Please see this thread for a more detailed explanation: Offline Installers: Invalid Digital Signatures The bottom line is that the software is correctly signed.   Your operating system is not able to validate it, because it lacks the necessary cryptographic support for any signature considered secure in the context of 2017.  I've provided a more detailed explanation and information on low-cost upgrade options in the thread above.
