I have tried to download Flash Player from the below link 

https://get.adobe.com/flashplayer/?no_redirect

But we get the failure as "Unknown Publisher" when installing. Please fix it and then give us a new version. Thanks heaps.

    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.
