Resolution

To troubleshoot these errors, you have to enable logging for two processes, and then try to install the updates again. When you enable logging, the actual error codes that are generated by Windows Installer are captured. As soon as the error codes are captured, you can determine the actual issue and the resolution for that issue. These errors will require you to contact Microsoft Support to resolve the issue. However, you have to do several things before you contact Microsoft Support.

To enable and collect the Windows Installer logs, follow the steps for your operating system.

Step 1: Enable Microsoft Installer logging and Windows Update verbose logging
