valdir - no tutorial, did not see the need - been using Paradox tables in Delphi as long as I've been using Delhpi (about 10 years)
Attached are my project.lpr, unit1.pas files (as text), and a screenshot showing the error, which occurs when I click the active checkbox in the Object Inspector. I'm used to seeing errors here, BUT, they usually relate to the table itself, rather than the engine!!
As to the location of the DLL I started off with it in the Lazarus path, but moved it when I first saw the error, the point being that Windows\System32 should be accessible everywhere. I believe there is still also a copy in the Lazarus directory, which should also be on the path.
