NSIS默認安裝目錄 - 要根據安裝選項進行選擇

Question

我幾乎是NSIS的新手;但我遇到了一個問題，我已經查看了我在本網站上可以找到的所有內容，以及使用Google搜索查找答案;到目前爲止，我什麼都沒有。

我有一個NSIS安裝包，我被要求擴大，以便它將安裝任何四個相關的程序。但是，儘管相關，他們每個人都應該安裝到不同的文件夾。

我有一個MUI_INSTALLOPTIONS_READ，它定義了四個（互斥）單選按鈕，並且工作正常;它會一直等到選擇該選項後才提示安裝位置。但它不會讓我爲每個應用程序設置不同的文件夾。

我在MUI_INSTALLOPTIONS_READ之後的每個分支中做的第一件事是將$ INSTDIR設置爲所選應用程序的默認路徑;所以我希望在調用InstallDir時使用該字符串作爲默認值;但它不 - 它是空白的。

當然，我不能在代碼中的InstallDir之前移動MUI_INSTALLOPTIONS_READ，因爲它必須位於Section中;並且我無法在MUI_INSTALLOPTIONS_READ之後移動InstallDir，因爲它不能位於節（或函數）中。我嘗試拆分包含MUI_INSTALLOPTIONS_READ的部分，以便它與下一部分之間存在一定的空間，並將InstallDir插入該空間中;但這並沒有改變。

任何人都知道一種方法來做我想做的事情？感謝您提供的任何建議。

嘗試在leave回調您的自定義頁面或pre回調目錄頁面設置$InstDir。我還建議您爲每個應用程序使用一個部分，然後在進入instfiles頁面之前完成所有配置。

也可以與無線輔助宏使用的組件頁面sections.nsh，而不是您的自定義頁面...
