After a couple more tries and a reboot, it now has installed. It looks to me as if the download was truncated or corrupted somehow, so it refused to install the file it had downloaded - but it didn't delete the file and didn't attempt to validate it. Regardless, there's something badly wrong that it can get into that state.
