From what I could find online, this error means there is something wrong with your installation of windows. It could be a missing or corrupt file. I would think that you would need to reinstall windows or revert to a restore point to fix it. You could also try this article which seems to suggest that you can fix it with a repair tool.

Before trying any method of fixing this error, I recommend that you backup any important data.
