The Wizard is used to install machine data for all users such as corporate address books (trusted identiies) and signature appearances. In the case of the addressbook (which stores signature data) if you deploy a common addressbook, all end users get the enterprise addressbook/ of you do not provide an addressbook.acrodata file, the application looks for any existing addressbooks on the end user's machine. The application looks for files in this order:

• \AppData\Roaming\Adobe\Acrobat\11.0\addressbook.acrodata
• \AppData\Roaming\Adobe\Acrobat\10.0\addressbook.acrodata
• \AppData\Roaming\Adobe\Acrobat\9.0\addressbook.acrodata
• C:\Program Files (x86)\Adobe\Acrobat 11.0\Acrobat\Replicate

Any found file is copied to the appropriate directory for the current install so that end user data is preserved.
