Architecture Mismatch Problems

If you encounter an error message similar to "The specified DSN contains an architecture mismatch between the driver and application", then the bitness of the application you are using to attempt to connect to the data store does not match the bitness of the driver that you are using. You might be attempting to use a 32-bit driver with a 64-bit application, or or a 64-bit driver with a 32-bit application. Make sure that the bitness of your application matches the bitness of driver that you are trying to use.

Note:

Applications in Microsoft Office 2007 and earlier are 32-bit only.

To determine the bitness of an application:

  1. Open the About dialog box for the application. For example, to open the About dialog box for Microsoft Office 2013 products, select the File tab in the ribbon, then click Account in the left pane, and then click the About [Application] button (where [Application] is the application name).
  2. In the About dialog box, look for the words 32-bit or 64-bit:
    • If the About dialog box contains 32-bit, then you must use a 32-bit driver to connect to that application.
    • If the About dialog box contains 64-bit, then you must use a 64-bit driver to connect to that application.

    For example, the following image shows the About dialog box for a 32-bit version of Microsoft Excel 2013.
