为什么NSIS安装程序在两个应用程序安装中运行两次,即使只选中了一个应用程序复选框?

请注意,我一直在研究为什么会发生上述情况,包括研究这些链接:

NSIS installer .onInit and un.onInit run twice because of UAC

https://github.com/Tribler/tribler/pull/2168

但是上面的UAC问题似乎不适用于我的案例,因为我没有使用那个插件。无论如何,我只是想知道,为什么整个脚本要运行两次?我最初打算以这个示例脚本为基础:

https://nsis.sourceforge.io/Two_installations_in_one_installer

但脚本设计最终发生了很大变化,包括不需要两层嵌套的复选框。
