如何在卸载时立即生成WIX执行命令

Question

我有一个使用WIX安装应用程序的java桌面应用程序。在安装时，WIX正在创建一个位于{...} / AppData / Local文件夹中的文件夹。然后，应用程序在执行应用程序期间使用子文件夹和文件填充此文件夹。

我们注意到在卸载应用程序时，不删除此文件夹（如果已填充，如果它是空的，则通过RemoveFolder elelemt删除），这会导致不愉快。

对此事的研究表明，RemoveFolder元素只能删除空文件夹，即。没有子文件夹和文件。为了解决这个问题，我提出了执行批处理文件的解决方案，该代码用于通过自定义操作删除整个文件夹，包括子文件夹和文件。我想把这个文件放在应用程序的安装路径中，这与放置我要删除的文件夹的位置不同。

打开安装/卸载应用程序的日志记录后，我发现此自定义操作未按正确的顺序执行，即。它在删除安装文件夹后执行，从而永远不会运行批处理文件。

这是我的WIX InstallExecuteSequence：

  <InstallExecuteSequence>

     <Custom Action='RemoveAlelionFolder' After="InstallFiles">
         Installed AND NOT UPGRADINGPRODUCTCODE
     </Custom>
      <RemoveExistingProducts After="InstallValidate"/>

  </InstallExecuteSequence>

  <CustomAction Id='RemoveAlelionFolder' ExeCommand='[INSTALLDIR]remove.bat' Directory="INSTALLDIR" Execute="deferred" Return='asyncNoWait' />

以下是安装/卸载日志文件的一部分：

解决了！

我必须运行自定义操作'After ='InstallInitialize'，以便它在代码流中的正确位置运行。

  <InstallExecuteSequence>
     <Custom Action='RemoveAlelionFolder' After="InstallInitialize">
         Installed AND NOT UPGRADINGPRODUCTCODE
     </Custom>
      <RemoveExistingProducts After="InstallValidate"/>
  </InstallExecuteSequence>
