For the past five days or so, Vivaldi browser has shown in PMP as needing an update, and it seems to do complete it. But there it is again the next day. So after tonight's try, I opened Vivaldi and checked for updates. It said I needed the one that PMPC says had been installed. What I noticed tonight, though, was the message with the install: "Install complete Exit Code 7" (it must have been there before). Screenshot attached.
