I recently activated Microsoft Essentials to protect my pc, however, the WiaTrace shows several errors:

How do I correct these reported errors?

Hi,
You probably downloaded that setup file from internet, i think it's corrupted. Try downloading again and reinstalling application should fix your problem.
