Dee, To my knowledge, the software can be installed on up to four computers so long as you are the primary user at all four and no more than one of them is being used at any one time. Or at least, that is the way it used to be, but I've admittedly not read the small print in the license information in awhile. Also, if you're not aware of it, there is a Family Atlas list that is just like this one only for FA software. Not used much though, and can use a little activity. . .such as posts like this one. :-) David E.

Is the 2006 software okay to use for Vista? Thanks, dee
