&gt;What does it mean and how can I load my Delphi 3 applications in Delphi 5? <br />

that means you need the source of all units,<br />
which are not part of the shipment from delphi<br />
<br />
compiled units from different delphi versions cannot linked mixed<br />
<br />

Shot in the dark: I'd recommend to remove all DCUs for those PAS, because IIRC Delphi will not rebuild files which are not changed if DCUs are present. Also Project-&gt;Build Project might help.

Thanks a lot.
