I had to fool around with this one a while until I figured it out.
I have Firebird (open source Interbase clone) running on the same machine. On a hunch I shut down the Firebird daemon and reinstalled Paradox 10 and everything was hunky dorie.
When I restarted the Firebird daemon, both products were happy.
I guess that Firebird looked enough like another instance of BDE to confuse the loader.
Case closed.
Sidebar- I used to use Paradox, Quatro Pro, Turbo C and Pascal back in the dark ages of DOS. They were cheap enough that a college kid could afford them and they actually worked. Borland made some really slick stuff. The other guys couldn't even spell IDE and Borland was selling them on 5 1/4" floppies.
Paradox is useful enough as a simple migration tool[ to pay $75-100 for it.
It's sad that fine products like these are fading. They are not bad products but they are badly marketed. If Corel were smart, they would sell them unbundled. They could probably get away with marketing it like a 30-day shareware trial download and make their money on the license and documentation.
As it is, you MUST buy WP Office Pro to get Paradox and that just isn't working.
