Hi,
The SQL Server Native Client (SQLNCLI) remains deprecated and it is not recommended to use it for new development work. Instead, use the new Microsoft OLE DB Driver for SQL Server (MSOLEDBSQL) which will be updated with the most recent server features. Refer to this MS document.
This is a forum that talking issues about MS product, Crystal report is a third party product, not a MS one, so contact the software vendor support.
Best regards,
Cathy
