22.7.0.76 problem on Vista

Since the upgrade to 22.7.0.75, and now, .76, NIS is telling me that my PC is not protected by SONAR advanced protection in the main Norton window.  When I go to the advanced settings icon, the slider for auto-protect is green (on) and the slider for SONAR is gray (but also in the on position).  What's the deal?

  If I'm on my admin account, I get the option to fix the problem on the main Norton window, but when it tries to fix it, it comes back with "not fixed."

  In the Windows Security Center it tells me that everything is running fine.  Live Update works, I can run complete scans, but why do I get the dreaded red X about the SONAR thing?   I'm running Vista with all the current updates as of May 2016 (haven't been able to get this months updates, possibly because of the new Norton update as well).  It seems like since the start of the year, Norton has become increasingly problematic for me.  Are they phasing out Vista support or what?
