inno-setup - Inno安装程序安装程序以verysilent模式提示

我正在使用/verysilent /suppressmessagebox /norestart运行安装程序来升级我的应用程序（Windows服务）。在PrepareToInstall()中，我有代码使用net stop <ServiceName>来检查和停止已经运行的服务实例。我记录net stop生成的输出，它表明服务确实已经停止。但是，有时，安装程序会提示：

消息框（中止/重试/忽略）：

安装程序无法自动关闭所有应用程序。建议您在继续之前使用需要由安装程序更新的文件关闭所有应用程序。

单击“重试”再试一次，“忽略”仍然继续，或者“中止”取消安装。

有两个问题：

为什么消息框以/verysilent模式显示？根据{{3}}，它不应以静默模式显示。根据{{3}}，我确实看到：

/ SILENT，/ VERYSILENT 指示安装程序保持沉默或非常安静。安装程序静默时，不显示向导和后台窗口，但安装进度窗口为。当设置非常安静时，不会显示此安装进度窗口。其他一切都很正常，例如显示安装过程中的错误消息，启动提示符（如果您没有使用DisableStartupPrompt或＆＃39; / SP - ＆＃39;命令行选项如上所述。
为什么RestartManager似乎仍然相信exe已经停止时正在运行？有没有其他人看到类似的问题，是否有推荐的方式？（比如，在net stop命令后添加5秒暂停）
