This "oops" message was the top-level error, but I was getting a lower-level error "The feature you are trying to use is on a network resource that is unavailable" when I tried to run the installer directly.
I followed a StackOverflow thread to this troubleshooting tool and used it. It fixed the problem, which appears to be a corrupted registry entry.
