When running an inventory scan on a device you see similar events to the example below within the Windows Event log surrounding MsiInstaller:
The informational alerts surrounding MsiInstaller on the scanned device stem from the Inventory Scanner accessing the Win32_Product WMI class. This class is accessed to obtain accurate and precise install date information for Microsoft Products and the informational alerts are a result of this. These messages will not affect machine functionality as they are explicitly informational.
Note: The logic for the Inventory Scanner to gather this data has been updated and the Win32_Product WMI class is no longer accessed in order to do so. These alerts should no longer occur in version 2016.3 SU3 and beyond.
