Issue
When running an inventory scan on a device you see similar events to the example below within the Windows Event log regarding MsiInstaller:
Cause
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.
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.
