I had a similar problem earlier this week. The cause was the MikTeX mirror I was using was reporting that versions of LaTeX elements were present, but when the updater would run from LyX to install missing things, it would fail. The errors show in LyX message console, but they aren't fatal. I discovered this by running the update/package manager myself outside of LyX.
The short term solution was to choose another LaTeX distribution mirror in MikTeX updater by running it outside LyX.
