I would advise you NOT to purchase the Generations Family Tree 8.5A. If you take a simple scan of the messages on this Generations board, you will see that almost all the current messages are from individuals using it with XP. The problems are to wild and crazy and to numerous to list all of them here. The patches, work arounds and non compatible software fixes do not seem to help the problems. Sorry, I used to love Generations also.
BTW: with Xp you can get your older versions of software to work. There is a way to select to run the sofware with the computer acting as an older version of Windows. Right click on the icon of the sofware Select properties under the compatibility tab you will find "compatibility mode" click on the box in front of "run this program in compatibility mode for" select the former version of Windows that you used to use or want it to run it in. It does work. I tried it on my older version of Generations. No it does not help the 8.5 version. Nothing does.
