When you have more than one version of Microsoft Access on the same computer, Microsoft Windows can only associate one version of Microsoft Access with the .mdb file extension. By default, the version of Microsoft Access that you installed most recently starts when you open an .mdb file directly by using a shortcut, an icon, Windows Explorer, or File Manager. If you want to open a database (.mdb) file in another version of Microsoft Access, you must start that version, and then open the database.
You can change which version of Microsoft Access is associatedwith the .mdb file name extension by using the following instructions.
NOTE: Windows 95 and Windows NT version 4.0 offer the Open With and Send To shortcut menu commands as alternatives to changing the .mdb file association. For more information about using these options, see the following articles in the Microsoft Knowledge Base:
