Inno Setup - Avoid displaying filenames of sub-installers

Question

I am trying to use the idea from Inno Setup - How to hide certain filenames while installing? (FilenameLabel)

The only sure solution is to avoid insta

Answer 1

The easiest is to give up on the standard [Files] and [Run] sections and code everything on your own in the CurStepChanged event fuction:

[Files]
Source: "dxwebsetup.exe"; Flags: dontcopy

[Code]

procedure CurStepChanged(CurStep: TSetupStep);
var
  ProgressPage: TOutputProgressWizardPage;
  ResultCode: Integer;
begin
  if CurStep = ssInstall then { or maybe ssPostInstall }
  begin
    if IsComponentSelected('DirectX') then
    begin
      ProgressPage := CreateOutputProgressPage('Installing prerequsities', '');
      ProgressPage.SetText('Installing DirectX...', '');
      ProgressPage.Show;
      try
        ExtractTemporaryFile('dxwebsetup.exe');
        StartWaitingForDirectXWindow;
        Exec(ExpandConstant('{tmp}\dxwebsetup.exe'), '', '', SW_SHOW,
             ewWaitUntilTerminated, ResultCode);
      finally
        StopWaitingForDirectXWindow;
        ProgressPage.Hide;
      end;
    end;
  end;
end;

This even gives you a chance to check for results of the sub-installer. And you can e.g. prevent the installation from continuing, when the sub-installer fails or is cancelled.

Then it's easier to use the PrepareToInstall instead of the CurStepChanged.

Another option is to display a custom label, while extracting the sub-installer.
