Welcome page not showing, SelectDir page is showing first instead

Question

I'm trying to make installer using Inno Setup.

And I want to show Welcome page first, then SelectDir.

This is CurPageChanged example code:

procedure CurPageChanged(CurPageID: integer);
begin
  if CurPageID = wpWelcome then
  begin
    HideComponents;
    WLabel.show;
    WizardForm.NextButton.Show;
    WizardForm.NextButton.Caption := 'Configure';
  end;

  if CurPageID = wpSelectDir then
  begin
    HideComponents;

    BmpFile.Bitmap.LoadFromFile(ExpandConstant('{tmp}\2.bmp'));
    WizardForm.DirEdit.Show;
    WizardForm.NextButton.Show;
    WizardForm.NextButton.Caption := 'Install';
    WizardForm.DirBrowseButton.Show;
    TasksSeparateBevel.Show;
    TasksSeparateBevel2.Show;
    InstallpathLabel.Show;
    DiskSpaceLablel.Show;
    ShortcutLabel.Show;
    ShortcutCB.Show;
    CreateDLabel.Show;
  end;

  if CurPageID = wpInstalling then
  begin
    HideComponents;

    MakeSlideShow;
    TimerID := SetTimer(0, 0, 10000, WrapTimerProc(@OnTimer, 4));

    WizardForm.CancelButton.show;
    WizardForm.ProgressGauge.show;
  end;
end;

But the SelectDir shows first then Install. Welcome page does not show!

Answer 1

The Welcome page is by default skipped since Inno Setup 5.5.7:

As recommended by Microsoft's desktop applications guideline, DisableWelcomePage now defaults to yes. ... The defaults in all previous versions were no.

To show it, you have to set:

[Setup]
DisableWelcomePage=no

Thought as mentioned in the quote above, the defaults are recommended, so you should follow them.
