要检查是否选择了某项任务，您可以使用IsTaskSelected功能。因此，为了满足您的要求，您可以写下这样的内容：

[Setup]
AppName=My Program
AppVersion=1.5
DefaultDirName={pf}\My Program

[Tasks]
Name: deletefolder; Description: "Delete a folder"; GroupDescription: "Group Description:"

[Code]
function NextButtonClick(CurPageID: Integer): Boolean;
begin
  // allow the setup turning to the next page
  Result := True;
  // if we are on the Additional Tasks page and the task is selected, then...
  if (CurPageID = wpSelectTasks) and IsTaskSelected('deletefolder') then
    // here call the RemoveDir or DelTree function depending on your needs
end;
