>I've already installed the VFP 7.0 in my Win2000 Pro. When I install the Delphi 6 Enterprise Edition, it's a warning that Delphi needs a different Just-In-Time debugger from VFP. Should I replace the VFP's Just-In-Time debugger by the Delphi's Just-In-Time debugger? What is the influence either use VFP's or Delphi's Just-In-Time debugger for both programs? Thanks for solving my problem.

Hmm, interesting. VFP doesn't have a JIT debugger. IOW, if your app runs into a problem, there isn't a way to break into it with the VFP debugger (unless you're running it from inside the VFP development environment). It's just a guess, but you should be just fine by letting Delphi put its own JIT debugger on there.
