Вопрос How to disable this effect on ISDone code?

[nizcoz]

nizcoz, check or add this:

[UninstallDelete]
Type: Filesandordirs; Name: {app};

This line already had it in my code. I am trying to cancel the installation (when decompression starts) with this code:

end;
    HideControls;
    WizardForm.CancelButton.Visible:=true;
    WizardForm.CancelButton.Enabled:=false;
  end;
  if (CurStep=ssInstall) and ISDoneError then begin
  Exec(ExpandConstant('{uninstallexe}'), '/VERYSILENT','', sw_Hide, ewNoWait, ResultCode);
  ExitProcess(0);
  end;
end;

But, when i press cancel and select ok, the uninstallation is not complete, the time to run

Exec(ExpandConstant('{uninstallexe}'), '/VERYSILENT','', sw_Hide, ewNoWait, ResultCode);

is not enough because the process is aborted before it is completed.
