The Family Archive Viewer is mainly associated with Family Tree Maker which is also owned by Genealogy.com. You might want to download version 6.0 from http://familytreemaker.genealogy.com/wftonline/http://familytreemaker.genealogy.com/wftonline/ and see if that will work for you.
UFT was discontinued around the middle of last year and the support has disappeared. Many of the UFT users have moved to other programs. Several are using TMG which you can check out at http\:www.whollygenes.com
