Nsis 两个应用程序的文件都安装在两个目标文件夹中

请注意，我最初创建了两个应用程序的安装程序，第一个应用程序是主应用程序，而第二个应用程序是license manager。也就是说，我确实删除了只有一层复选框的嵌套复选框。仅供参考，我也参考了这篇文章：

我遇到的问题是，当我运行安装程序时，

MyApp

和

FlexLM

中的所有文件都安装在

$PROGRAMFILES64\${PRODUCT\u NAME}

文件夹和

C:\${FLEX\u DIR}

中。因此，当我安装两个应用程序时，看起来MyApp安装中同时执行了

SEC1

和

SEC3

，而

FlexLM

安装中同时执行了SEC1和SEC3：

我刚刚测试了维基上的代码，效果非常好。您在

SelectFilesA

/

B

中注释掉了循环，因此难怪您的示例中的部分逻辑被破坏

您还有一些其他问题：

StrCpy $MyAppCheckboxState ${BST_CHECKED}
${If} $MyAppCheckboxState == ${BST_CHECKED}

这毫无意义，这永远是真的

另外，

CreateShortcut“$SMPROGRAMS\${PRODUCT\u NAME}.lnk”“$PROGRAMFILES64\${PRODUCT\u NAME}\${PRODUCT\u NAME}.exe”

是错误的，它应该是

CreateShortcut“$SMPROGRAMS\${PRODUCT\u NAME}.lnk”“$InstDir\${PRODUCT\u NAME}.exe”

更新2:

这是我的最终解决方案——非常感谢。它可能不是最理想或最优雅的解决方案，但它能满足我的需要。我试着把这个添加到我的问题中，但出于某种原因，所以不让我这么做

前几天我建议您不要使用多个InstFiles页面，现在我们可以了，也许在一个安装程序脚本中安装两个应用程序不是最佳做法，但也就是说，NSIS网站上有一个脚本示例，它在一个安装程序脚本中安装两个应用程序，那么，这难道不意味着这实际上是由Nullsoft支持的吗？看，这是一个维基，任何人都可以编辑。多个InstFiles页面可以正常工作，只是因为该场景没有被特别阻止，但它确实需要您手动处理部分。我认为最好的调试方法是在每个InstFiles页面之前添加一个components页面，并找出为什么部分的状态不正确。我仍然不明白为什么你坚持要有两个InstFiles页面。有两个目录页和一个InstFiles页非常简单…我注释掉循环的原因是，最初复选框嵌套在两个级别中，但我只需要一个复选框级别。感谢您指出有关${BST_CHECKED}的问题。然后如何获取复选框是否选中的值？抱歉，我不熟悉NSIS脚本当我看这里时，我看到您可以使用${NSD_GetState}获得复选框状态，但我不知道MUI_页面_组件中复选框的名称/句柄，而在SO链接中，复选框称为$hwndCheckbox，因为它是显式创建的。组件页面不使用复选框，它是一个树状视图，但您可以随时使用

${If}${SectionIsSelected}${SEC1}

进行检查。如果您只需要一个级别，请删除分区组。谢谢。如果我决定取消选择“MyApp”怎么办？然后，如果我使用

${if}${SectionIsSelected}${SEC1}

它仍然会显示目录选择对话框并创建MyApp目录，尽管它是空的。如何使此目录选择对话框不显示？在第一个目录页的MUI_页面_CUSTOMFUNCTION_预回调函数中，如果调用了

Abort

，则跳过该页。
