.exe 使用 Windows 调度程序成功启动，但不会在 visualcron 上引发错误

Question

当我登录机器运行 exe 时，脚本工作正常。但是当我在 VisualCron 上安排 .exe 时，它​​会引发异常。我在 Windows 调度程序上尝试了相同的 .exe，我能够运行该作业。

错误详情如下。我该如何解决这个问题。请帮忙。

默认情况下，所有任务都由 VisualCron 服务在后台执行，通常以 SYSTEM 帐户运行。如果出于某种原因，您的可执行文件试图显示一个界面，它将阻止系统，因为在后台没有桌面可以显示或与消息交互。

您可能想知道它引发错误的原因。但如果它在 VisualCron 之外工作，原因通常是你不能；

1. 使用凭据
2. 尚未在凭据设置中检查“加载配置文件”
