Cause
A Windows security update rolled out in October 2017 which updated the Jet.OLEDB 4.0 provider. It is an old MS component we use to convert an Excel spreadsheet into xml.   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)."  In the case of web applications, it was XML files that failed.

Resolution
Microsoft has released a November security rollup that resolves this issue.  If you see this issue, apply the update from the link below:
