It can be downloaded from http://devzone.advantagedatabase.com/dz/content.aspx?Key=20&Release=16&Product=8&Platform=6 . Once you have install Advantage Data Architect, follow these step to free your target adt files.

1.       Click on new connection wizard

2.       Create a connection to a directory of existing tables

3.       Provide DatabaseName of your choice and then provide correct path of folder where adt files are located on your hard drive and press finish.

4.       Once you have created connection, it will start showing adt tables BUT still you can’t open or export these tables as these are bound to directory.

5.       To free these tables, click on Tools -- > Free Data Dictionary Bound Tables

6.       Provide adt file name with its complete path and press OK button.

7.       Your adt table is now free. Now you can open it in Data Architect. You can export or you can close Data Architect and import this table from SQL Server Import Wizard.
