  • sqlsrv32.dll is 15 years old and exists only for legacy reasons. You should preferrably use ODC 13.1 SQL Server driver which is the latest version.

  • Hi nitraw26,

    The ODBC driver DLL "SqlSvr32.dll" belongs to MDAC(Microsoft Data Access Components), it is too old to support recent operation system. If you want to know more information about MDAC, you may read these articles for better understanding.

    Using the SQL Server Native Client Header and Library Files( the content is under heading "Component Names and Properties by Version")

    Microsoft Data Access Components (MDAC) Installation( the content is under heading "Introduction")

    In your reply, you said that you had got error messages from your application. Could you please share us your error messages, so that we could know which situation you have come across. I guess the problem is caused by version incompatibility. For more information, you may refer to these articles.
