inno-setup - Inno Setup DelTree 不删除顶级文件夹

Question

我连续三个调用 DelTree()CurUninstallStepChanged()是usPostUninstall这样的：

if IsDeleteAData then
begin
  Res:=DelTree(AppData+'\ADirName', true, true, true);
  Log('Delete '+AppData+'\ADirName result: '+IntToStr(Integer(Res)));
end;

if IsDeleteBData then
begin
  Res:=DelTree(AppData+'\BDirName', true, true, true);
  Log('Delete '+AppData+'\BDirName result: '+IntToStr(Integer(Res)));
end;

if IsDeleteCData then
begin
  Res:=DelTree(AppData+'\CDirName', true, true, true);
  Log('Delete '+AppData+'\CDirName result: '+IntToStr(Integer(Res)));
end;

A 和 B 删除所有应有的内容。但是，C 不会删除顶级目录（实际的CDirName），但会删除内容，如果CDirName为空，它将删除CDirName目录本身。

如果我启用日志记录，我得到的结果是当它不删除顶级目录时结果为 0。

它在 6.0.3 中执行此操作，现在已更新到 6.2.0，并且仍在执行此操作。有什么想法或方法可以深入挖掘吗？我过去从来没有遇到过问题DelTree()。

我捕获了进程信息，它基本上只是说不能删除：

然后我尝试添加另一个RemoveDir，usDone但仍然给出：
