从[代码]中退出Inno Setup安装 [英] Exit from Inno Setup installation from [Code]

问题描述

是否可以从使用Inno Setup创建的安装程序的[Code]部分中的功能中退出安装?

Is it possible to exit the installation from a function in the [Code] section of an installer created with Inno Setup?

我对设置退出代码不感兴趣，我想要做的是对需求进行自定义检查，如果以前没有安装该需求，则退出安装.

I'm not interested in setting the exit code, what I want to do is perform a custom check for a requirement, and exit the installation if that requirement was not previously installed.

推荐答案

如果您在以下事件中，可以使用 Abort():

You can use Abort() if you are in these events:

InitializeSetup
InitializeWizard
CurStepChanged(ssInstall)
InitializeUninstall
CurUninstallStepChanged(usAppMutexCheck)
CurUninstallStepChanged(usUninstall)
