danielstern96, can you tell us if this CD was created by an older software, or what?
If it was simply images written to CD, these should be viewable.
My suspicion is that this family tree CD was created with some type of software, designed for an earlier version of Windows. If you happen to have Windows 7 Pro or above, MS offers a free virtual XP machine, otherwise known as Windows Virtual PC with XP Mode. If the software was designed or works with XP, you can install it to XP Mode, if it requires a license, you'll need both the installer (.exe) file & license key. Note that we cannot promise this will work, depending on the age of the software.
I've ran across a couple of things myself that wouldn't open in Windows 7, however the CD's were created in the 90's. This would predate XP.
