NSIS默认安装目录 - 要根据安装选项进行选择

Question

我几乎是NSIS的新手;但我遇到了一个问题，我已经查看了我在本网站上可以找到的所有内容，以及使用Google搜索查找答案;到目前为止，我什么都没有。

我有一个NSIS安装包，我被要求扩大，以便它将安装任何四个相关的程序。但是，尽管相关，他们每个人都应该安装到不同的文件夹。

我有一个MUI_INSTALLOPTIONS_READ，它定义了四个（互斥）单选按钮，并且工作正常;它会一直等到选择该选项后才提示安装位置。但它不会让我为每个应用程序设置不同的文件夹。

我在MUI_INSTALLOPTIONS_READ之后的每个分支中做的第一件事是将$ INSTDIR设置为所选应用程序的默认路径;所以我希望在调用InstallDir时使用该字符串作为默认值;但它不 - 它是空白的。

当然，我不能在代码中的InstallDir之前移动MUI_INSTALLOPTIONS_READ，因为它必须位于Section中;并且我无法在MUI_INSTALLOPTIONS_READ之后移动InstallDir，因为它不能位于节（或函数）中。我尝试拆分包含MUI_INSTALLOPTIONS_READ的部分，以便它与下一部分之间存在一定的空间，并将InstallDir插入该空间中;但这并没有改变。

任何人都知道一种方法来做我想做的事情？感谢您提供的任何建议。

尝试在leave回调您的自定义页面或pre回调目录页面设置$InstDir。我还建议您为每个应用程序使用一个部分，然后在进入instfiles页面之前完成所有配置。

也可以与无线辅助宏使用的组件页面sections.nsh，而不是您的自定义页面...

!include MUI.nsh 
!include LogicLib.nsh 
Page Custom MyCustomPageCreate MyCustomPageLeave 
!insertmacro MUI_PAGE_DIRECTORY 
!insertmacro MUI_PAGE_INSTFILES 
!insertmacro MUI_LANGUAGE English 

Function .onInit 
InitPluginsDir 
WriteIniStr "$PluginsDir\page.ini" Settings NumFields 2 
WriteIniStr "$PluginsDir\page.ini" "Field 1" Type RadioButton 
WriteIniStr "$PluginsDir\page.ini" "Field 1" Text "App 1"

Function MyCustomPageCreate 
!insertmacro INSTALLOPTIONS_DISPLAY "page.ini"

Function MyCustomPageLeave 
!insertmacro MUI_INSTALLOPTIONS_READ $0 "page.ini" "Field 1" "State"
