When using the Jet Professional Excel add-in with SQL Server 2012/2014, and testing the connection to either a NAV SQL data source or a SQL data source, an "Provider cannot be found" message may be displayed.
Complete text of error message is:
Provider cannot be found. It may not be properly installed.
This error is generally encountered when either:
- the SQL Server Native Client driver (aka "provider") is not installed or
- the driver installed on the computer is not fully compatible with the version of SQL Server that is being accessed.
SQL Server Clients are available directly from Microsoft.
