Thanks for that, Warren.
I discovered the correct road to success on my issue.
The secret of the universe was to upgrade PPCC to its latest version. That allowed it to boot up properly and, bonus, recognize the card itself in so far as it now runs video, and the program allows me to place that video on the time line. (In past I'm sure I had to specify the card and a few other video parameters before video worked.)
However, the video does not run with sound. Something I expect I will hopefully be able to trouble shoot. (It also seems maybe the upgraded Premiere Pro has a slightly different process to ingest video? I don't recall an "ingest button" that can be invoked. Then I also see the more familiar and similar "import" on right click.)
In any case, I was first relieved that my camera actually did record audio as the video plays properly with audio in Windows Media. So hopefully it will be just a matter of time before I figure out what has happened to the Pr audio. I note that there is no audio placed on the time line so I suspect some setting or an incorrect ingest process.
Soap box: Sigh. I wish software companies would make their software systems into "expert systems" such that we users do not have to futz around like this. I know some people just love to understand 350 page user manuals but I just want results. At the very least, when I hover over a button, detailed explanations should be right there in context. It chokes me that Premiere Pro cannot figure out these problems for me or at least give me some clues as to what is wrong here. Such a pain. We are still in the caveman days of software. /soapbox.
