问题描述

我正在开发一个InnoSetup项目，我想知道如何始终安装一个组件(比如说"Acrobat Reader")，但是不允许取消选中组件列表中的该项目.
我不希望用户取消选中它.

I'm developing a InnoSetup project and I'm wondering how to always install a component (let's say 'Acrobat Reader') but don't allow to uncheck that item in the list of components.

Generally, a component is selected when the selected installation type is listed in the Types parameter of its entry. So if you list all the available installation types there, it will be selected always.

要禁用该组件以使用户无法修改其状态，您需要包括 fixed 条目的标志.

In your comment you've asked how to disable a task entry. As far as I know, there is no direct way to do this and the only way I could come up with is doing this in code from the CurPageChanged event:

[Setup]
AppName=My Program
AppVersion=1.5
DefaultDirName={pf}\My Program

[Tasks]
Name: something; Description: "Install something"

[Code]
procedure CurPageChanged(CurPageID: Integer);
begin
  // the ItemEnabled property uses a 0 based index for item access, so the following
  // code you can read as, if we have entered the tasks selection page, disable the
  // first tasks list item
  if CurPageID = wpSelectTasks then
    WizardForm.TasksList.ItemEnabled[0] := False;
end;
