How to skip custom page based on setup type in Inno Setup

Question

I\'m building my setup with server and client installation/setup types. I need to skip or hide a custom page if user choose server type. Server type only have a custom page

Answer 1

In ShouldSkipPage event function, compare the PageID against the TWizardPage.ID of the custom page. And use WizardSetupType support function to test the selected setup type.

var
  Page: TWizardPage;

function ShouldSkipPage(PageID: Integer): Boolean;
begin
  Result := False;

  if Page.ID = PageID then
    Result := (WizardSetupType(False) <> 'server');
end;

And obviously, your custom page must show after the "Select Components" page, not before:

Page := CreateCustomPage(wpSelectComponents, ...);

Alternatively, you can handle TWizardPage.OnShouldSkipPage of the custom page.
