16 bit DLL calling form Delphi 3.0

I'm working with Delphi 1.0 and a library to manipulate an I/O aquisition
card. When I buy Delphi 3.0 and translate my project, the DLL don't work
and Windows says "DLL is damaged and must be reinstalled", and Delphi
Project don't run saying "Unable to create the process".

I tried diferent kinds of translation, but none works.

Any have a solution.

Thanks

And none will. Essentially you can not call a 16-Bit DLL directly from
a 32-bit Application (and vice versa).

There are thunking-mechanisms that can do what you are trying to do but
I haven't used them. If someone has a solution (by way of a unit or
instructions or component) I would certainly be most interested.
