I'm trying to create an ODBC data source. Goal is to import data from Microsoft Access database. Following are General source data format.

DSN Type: System DSN

Connection String: Driver=Driver do Microsoft Access (*.mdb);DBQ=Z:\ESI_Data.mdb;Description=ESI database;DriverId=25;FIL=MS Access;PWD=;SafeTransactions=0;UID=Admin;ImplicitCommitSync=;MaxBufferSize=2048;PageTimeout=5;Threads=3;UserCommitSync=Yes;

Validate:

System Name: xxx

Error Message when Validate is: Test Connection failed-ERROR[IM002][Microsoft][ODBC Driver Manager]Data source name not found and no default driver specified.
