If wizards, like the Label Wizard, don’t open in the Word Document Gallery, Visual Basic for Applications (VBA) might not be installed. To install VBA, you’ll need to reinstall Office.
If you choose a standard install, VBA will be automatically installed.
If you choose a custom install, make sure VBA is included:
On the Custom Install screen, click the arrow next to Microsoft Office 2011 and make sure Visual Basic for Applications is checked.
