Sets the value of properties that are applied during Office installation. You can customize Setup property values only when Office is first installed on a user's computer; values set in a Setup customization file do not take effect if you apply the file to an existing installation.
To add a property value, click Add. To modify a property that you have added, select the property, and then click Modify. To remove a property that you have added, select the property, and then click Remove.
For more information about properties and their values, see Setup properties in Office 2010 in the Microsoft Office 2010 Resource Kit.
