Windows 10 says CorelDraw X4 is not compatible, What are the alternatives short of the latest (expensive) version?

I've been using CorelDraw since the early 90's. I don't use many features, X4 or even earlier versions do what I need. Windows 10 says CorelDraw X4 it is incompatible. I have a modest number of .cdr files that I would really like to use. What are the alternatives short of the latest (expensive) version?

I attempted to install X4 in my Windows 10 partition and Windows said it would damage my computer, wow that's not nice.
I did install CorelDraw8 (circa 1997) but it wouldn't run.
