DirecTV Video Player (VideoGuard 3.0) for Online viewing not installing

Starting over since the Forum closed the conversation.

While trying to view DirecTV content from my laptop or desktop computer.  Neither box will install VideoGuard 3.0  (VideoGuard completes, DirecTV web interface says it has installed, but first use says that it is not installed and directs me to the download)  I have the same problem on my iMac and MacBook Air (both running Monterey 12.0.1 and Safari 15.1)  It also happens on Firefox 95.0.2.  Clearing cache, browser, and system restarts have no effect.  iPad.iPhone  app operates normally.  There is no 'app' on a desktop (iMac) or laptop (MacBook).  VideoGuard 13.0.dmg does not have an 'uninstall' option.  

VideoGuard relies on Flash, which was discontinued last year.  That said, the DTV employee on chat directed me to a couple of websites for a workaround, but these alternate methods were for Windows based computers. [e.g., https://direc.tv/3qAHT6g 

Has anyone come up with a solution from either DirecTV or a DTV customer?  Not being able to stream on my Mac desktop/laptop is in direct conflict with their advertising and I am not getting the service I signed up for.  My iPad and iPhone works as advertised, but the desktop or laptop does not.
