You will need the Family Origins V 10 installation CD, if that will help find it. RootsMagic, the successor program to Family Origins, will open a Family Origins date base file but will not open a back-up (*.zip) file. A few folks still monitor the RootsWeb Family Origins mail list and may have some ideas.
