The Database Connectors interface for MSSQL is an add-on module. The installation includes a .DLL file that is detected at run time. It is not necessary for 32-bit users to relink the run time system.
Typically, the setup is one of a client machine using a Database Connectors connector to access a SQL database on a separate server; however, your SQL server and your client can be on the same machine. The Database Connectors interface can be executed on a machine that is running any supported 32-bit Windows platform from Microsoft.
See To Install Database Connectors for Microsoft SQL Server for details on client and server configuration, regardless of how you are set up.
