If you try to open the UTILITY.MDA file, you may receive the following error message:
The database "UTILITY.MDA" is already open as a library database.

To open the UTILITY.MDA file, you must create a copy of UTILITY.MDA, rename the copy, and then open it in Microsoft Access.

NOTE: This behavior no longer occurs in Microsoft Access version 7.0.


Use the following steps to open the UTILITY.MDA file.

NOTE: UTILITY.MDA is a collection of tables, forms, and modules used by Microsoft Access. You should always have a backup copy of UTILITY.MDA; this is a vital database to Microsoft Access and any changes in it may result in unexpected behavior.
  2. In Microsoft Access, open UTILITY.SAV by choosing Open from the File menu.
  3. Choose OK when the following error message is displayed:
    Tried to load module with duplicate procedure definition: <procedure name>
After you make any changes to the copy of UTILITY.MDA, you can rename the original UTILITY.MDA file and substitute the edited copy of the UTILITY.MDA file for the one that Microsoft Access uses when the application is opened.
