To check the ODBC SQL Server driver version (32-bit ODBC)
In the ODBC Data Source Administrator, click the Drivers tab. Information for the Microsoft SQL Server entry is displayed in the Version column.To verify the driver version number:
- From the Start menu, go to ODBC Data Sources.
- Click the Drivers tab and then find the Simba SQL Server ODBC Driver in the list of ODBC drivers that are installed on your system. The version number is displayed in the Version column.
The 64-bit version of the Odbcad32.exe file is located in the %systemdrive%WindowsSystem32 folder.
Download and install the ODBC driver
- To download the ODBC driver, see KB0540707.
- Download the ODBC driver version compatible with your computer's operating system and the application you are using to query the database.
- Right-click the executable and select Run as Administrator to launch the installer.
- Click Next.
A data source name (DSN) is a data structure that contains the information about a specific database that an Open Database Connectivity ( ODBC ) driver needs in order to connect to it. User and system DSNs are specific to a particular computer, and store DSN information in the registry.
Open the Command Prompt, or press the WIN + R keys to open the Run dialog box. Type odbcad32 and press Enter. If you're running Windows 10 64-bit, this should launch ODBC Data Source (64-bit). Otherwise, it will open ODBC Data Source (32-bit) instead.
- Go to Start > Settings > Control Panel.
- Open the ODBC icon.
- The User DSN tab appears. Click Add.
- The Create New Data Source window appears. Select the appropriate driver and click Finish.
- The Data Source Setup window appears for that driver.
- Click Select.
- The Select Database window opens.
- Click OK.
An ODBC driver uses the Open Database Connectivity (ODBC) interface by Microsoft that allows applications to access data in database management systems (DBMS) using SQL as a standard for accessing the data. ODBC permits maximum interoperability, which means a single application can access different DBMS.
To link to your data:
- In Access, select the External Data tab in the ribbon and then click ODBC Database.
- Select Link to the Data Source by Creating a Linked Table and then click OK.
- In the Select Data Source dialog box, select the Machine Data Source tab, then select your DSN from the list, and then click OK.
How to Update Your ODBC SQL Driver
- Navigate to the Microsoft website and download the latest Microsoft data access center (MDAC) program.
- Save the file to your desktop.
- Double click on the downloaded file and click on the "Install" button.
- Click on the location of your hard drive containing the new ODBC SQL driver when prompted during the installation.

To modify a data source for Windows
- Open the ODBC Data Source Administrator. Click the appropriate DSN tab.
- Select the Oracle data source you want to modify and then click Configure. The Microsoft ODBC for Oracle Setup dialog box appears.
- Modify the applicable data source fields, and then click OK.
Information
- Open the library.
- Right click in the library and choose Properties.
- In the "Data Source" tab, review the "Primary data source" field to see which DSN is being used.
- Choose Start (> Settings, on Windows XP or Windows 10) > Control Panel > Administrative Tools > Data Sources (ODBC)
The . dsn file is a text file that you can view in any text editor, such as Microsoft Notepad. The File DSNs are stored by default in the following location:Program FilesCommon FilesOdbcData Sources folder.
To fix this problem, the ODBC Driver settings need to be adjusted. Follow these steps: Click Start > Settings >Control Panel > Administrative Tools > Data Sources (ODBC). Click the "System DSN" tab in the ODBC Data Source Administrator Window.
Open Database Connectivity
