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.

Or

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.

 Or

 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.
