procedure CloseBtnOnClick(Sender: TObject);
begin
  if WizardForm.CurPageID = wpInstalling then
  begin
    SuspendProc;
    ExitForm.Show;
  end else
    ExitForm.Show;
end;

How to achieve smoothness of the progress bar and its accuracy when Isarcextract is not used?

ProgressBar.SetValue(WizardForm.ProgressGauge.Position, 1000);

And how to roll back everything when canceling the installation when Isarcextract is not used??
I would like if you don't mind a working example

perhaps this will work for you..
