Register Components in Delphi 5

i have a newly created package, wich contains 1 unit.

in this unit is the following code

{ ... }

procedure register;

implementation

procedure register;
begin
  ShowMessage('Registering...');
  RegisterComponents(PalletPage, [TRCKComponent]);
  RegisterPropertyEditor(TypeInfo(TAboutString), TRCKComponent, 'About', TAboutProperty);
end;

{ ... }


i compile the package, then i install the package. (no errors or warnings)

Delphi says 'Package installed' ...

but it never calls the register procedure, so the component never is registered.

what am i doing wrong?
