Thanks Steven. I solved it. They sent me detailed screenshots of the
install CD and a readme file and I found suspicious folders - DISK1_ID,
DISK2_ID etc. for 4 disks. I believe Pdox 7 was the last Paradox that
came on 4 floppies. I confirmed it by reading the README.WRI file.
Paradox 7. (Who has a readme.wri file any more?)

That explains why it won't install on Windows 10. It's 16bit.
