On the side note, what odbc interface you used to create connection
To manage a data source that connects to a 32-bit driver under 64-bit platform, use c:\windows\sysWOW64\odbcad32.exe. To manage a data source that connects to a 64-bit driver, use c:\windows\system32\odbcad32.exe.
If you use the 64-bit odbcad32.exe to configure or remove a DSN that connects to a 32-bit driver, for example,
Driver do Microsoft Access (*.mdb), you will receive the following error message:
The specified DSN contains an architecture mismatch between the Driver and Application
To resolve this error, use the 32-bit odbcad32.exe to configure or remove the DSN.
A data source associates a particular ODBC driver with the data you want to access through that driver. For example, you might create a data source to use the ODBC dBASE driver to access one or more dBASE files found in a specific directory on your hard
disk or a network drive. Using the ODBC Data Source Administrator, you can add, modify, and delete data sources, as described in the following table.
