You may encounter errors with your ACCDE/MDE files and/or wizards after installing the March update for Office 2010 (KB3085515)


After installing the March public update for Office 2010, you may encounter problems with your Access 2010 database files.

March 8, 2016, update for Office 2010

When attempting to launch the Access wizards, you may receive an error.  Examples:

This feature isn't installed, or has been disabled.

To install this feature, rerun the Microsoft Access or the Microsoft Office Setup program or, if you're using a third-party add-in, reinstall the add-in. To reenable this wizard, click the File tab, and then click Options. Click Add-Ins, and then the Manage list, click Disabled Items, and then click Go.


Microsoft Access can't start the wizard, builder, or add-in.

* The library database containing the wizard builder, or add-in may not be installed. Point to Add-ins on the Tools menu, and then click Add-in Manager to see if the library database is installed.

* The wizard, builder, or add-in code may not be compiled and Microsoft Access can't compile it. There may be a syntax error in the code.

* The key for the add-in in the Windows Registry file may be incorrect.


 The code contains a syntax error, or a Microsoft Access function you need is not available.

If the syntax is correct, check the Control Wizards subkey or the Libraries key in the Microsoft Access section of the Windows Registry to verify that the entries you need are listed and available.

If the entries are correct, either you must correct the Microsoft Access Utility Add-in, or the file acWzlib or this wizard has been disabled. To reenable this wizard, run Microsoft Access or Microsoft Office Setup again to reinstall Microsoft Access. Before you reinstall Microsoft Access, delete the Windows Registry keys for the Microsoft Access Utility Add-in and acWzlib.


When attempting to open or run code in an ACCDE, ACCDR, MDE file that was compiled in an earlier version of Access, you may receive an error.  Examples:

 The expression On Click you entered as the event property setting produced the following error. File format no longer supported.

* The expression may not result in the name of a macro, the name of a user-defined function, or [Event Procedure].

* There may have been an error evaluating the function, event or macro.
