Install attempt on Windows 10 brings up a Chrome Update

First time having this problem (I had Brave on an earlier Win 10 computer).

After accepting the user agreement, I get some teeny window with a blue Chrome emblem, and a button which reads “Update”. Not having been prompted with any other kind of next step, I shrug and click “Update”, only to watch the little circle of dots spin around endlessly to prep something that never happens.

What’s issue here, and what can I do?
