This seems to be an ongoing issue with 11.7.0.669. I have upgrade 120 machines to it when it first came out. So far, this update issue has happened on maybe 7 machines. All at different times. Some laptops, some desktops, some on network, some coming from a VPN. Reinstalling DOES fix the issue on the one machine, but it just hits another a few days later. One happened last Thursday, and on Monday there was another.
