Known issues in this update

Symptom	Workaround
Installing this update may cause applications based on the Microsoft JET Database Engine (Microsoft Access 2007 and older or non-Microsoft applications) to fail when creating or opening Microsoft Excel .xls files. The error message is, “Unexpected error from external database driver (1). (Microsoft JET Database Engine)".	Download and install the Microsoft Access Database Engine 2010 Redistributable, and then modify the DB connection strings in Microsoft Excel to use ACE as a provider. Example: Change Provider=Microsoft.Jet.OLEDB.4.0 to Provider=Microsoft.ACE.OLEDB.12.0.Microsoft is working on a resolution and will provide an update in an upcoming release.
After installing KB4041693, package users may see an error dialog that indicates that an application exception has occurred when closing some applications. This can affect applications that use mshtml.dll to load web content. The failure only occurs when a process is already shutting down and will not impact application functionality.	This issue is resolved in KB4048961.
