InnoSetup，在运行时更改Uninstallable属性的行为? [英] InnoSetup, change the Uninstallable property behavior at runtime?

问题描述

场景

我已经创建了一个安装程序，该安装程序将出于教育目的安装恶意软件应用程序，该安装程序包含以下两个任务:

I have created an installer that will installs a Malware application for educative purposes, the installer contains these two tasks:

[Tasks]
Name: hidden; Description: Hidden mode; GroupDescription: Installation Mode
Name: visible; Description: Visible mode; GroupDescription: Installation Mode

这意味着对用户执行隐藏安装(隐藏的目录和文件并进行卸载，使其成为安装程序)，或对用户执行可见的安装(常规目录和文件以及Uninstallable = True).

This means, performs a hidden installation for the user (hidden dirs and files and make uninstallabe the installer), or a visible installation (normal dirs and files and Uninstallable=True).

问题

我默认设置了Uninstallable=True，但是如果用户选择hidden任务，那么我想避免创建卸载程序.

I've set the Uninstallable=True by default, but If the user selects the hidden task then I would like to avoid the uninstaller creation.

我该怎么做呢?

推荐答案

您可以使用 Uninstallable 指令文档:

You can use the code shown in the Uninstallable directive documentation:

[Setup]
...
Uninstallable=not IsTaskSelected('hidden')

[Tasks]
Name: hidden; Description: Hidden mode; GroupDescription: Installation Mode
Name: visible; Description: Visible mode; GroupDescription: Installation Mode

或者，如果您需要用可重用函数编写的更复杂的语句，或者访问某些脚本代码元素，则可以编写一个函数，例如:

Optionally, if you'd need more complex statements written in reusable function, or access some of the scripting code elements, you could write a function, e.g.:

[Setup]
...
Uninstallable=IsUninstallable

[Tasks]
Name: hidden; Description: Hidden mode; GroupDescription: Installation Mode
Name: visible; Description: Visible mode; GroupDescription: Installation Mode

[Code]
function IsUninstallable: Boolean;
begin
  Result := WizardSilent or not IsTaskSelected('hidden');
end;
