Question

我在尝试取消应用程序时尝试执行自定义操作。这些应该在安静模式下完成。因此，我使用了那部分代码来实现它：

<?xml version="1.0"
      encoding="utf-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
    <Fragment>
        <Property Id="APPFOLDER">
            <RegistrySearch Id="PATH"
                    Key="Software\[Manufacturer]\[ProductName]"
                    Root="HKLM"
                    Type="raw"
                    Name="InstallPath" />
        </Property>
        <CustomAction Id="CleanupAppDirCmd"
                      Property="CleanupAppDir"
                      Value='rmdir /s/q "[APPFOLDER]"'
                      Execute="immediate"/>
        <CustomAction Id="CleanupAppDir"
                      BinaryKey="WixCA"
                      DllEntry="CAQuietExec"
                      Execute="deferred"
                      Return="ignore"
                      Impersonate="no"/>
        <InstallExecuteSequence>
            <Custom Action="CleanupAppDirCmd"
                    After="CostFinalize"/>
            <Custom Action="CleanupAppDir"
                    After="RemoveFiles">
                REMOVE="ALL"
            </Custom>
        </InstallExecuteSequence>
    </Fragment>
</Wix>

但没有任何反应。完成卸载后，该目录仍然存在。 uninstall-log告诉我以下内容：

我已尝试对CleanupAppDirCmd的值进行多项更改，但没有任何效果。我做错了什么？

rmdir不是可以执行的EXE，它是cmd.exe内部的shell命令。

我建议查看RemoveFolderEx Element (Util Extension)。它是一个更好的解决方案，包括在安装失败或取消时回滚删除。（非常重要）

WiX 3.8 CAQuietExec和命令字符串
