I have the original Blockbase program and Foundation Factory, also old DVD's from quilt books like Farmer's Daughter. I got them all working on the newer Widows computer by selecting open with (whatever the oldest version was). There were several options. I looked up how to find this online when I got a new computer. The newer programs are downloadable from online as most new computers do not have the dvd drive. I didn't want to rebuy the ones I already paid for.
