Hey ardee321, 

This issue may occur if there is corruption in the Component Based Servicing (CBS) manifest. 

Resolution: 

To resolve this issue follow the steps in method 1. If method 1 does not resolve the issue, continue to method 2.

Method 1: run the System Update Readiness tool (Checksur.exe)

  1. Download and run the System Update Readiness tool. This tool runs a one-time scan for inconsistencies that may prevent future servicing operations. For more informationabout how to download and run the Checksur.exe tool, click the following article number to view the article in the Microsoft Knowledge Base:

  1. Try to install updates again.

Note After you run the tool, the Checksur.log file is saved in the following location: %systemroot%\Logs\CBS

In a default installation of Windows, %systemroot% represents the Windows directory.
