You can download a "viewer" from the Family Tree web site. I works with the old CDs. Thanks, Donna How does one view these now? I have seven of the blasted things and I can't get them to open. The ones I have are old, but they worked for several years on more than one computer. Now I have Windows XP home on a Sony 620G and I can't read the information that I have already paid for. Blast !!!!
