.net - ClickOnce 部署 CheckForDetailedUpdate 抛出异常

Question

我有一个 24/7 无人值守的应用程序。它是通过 ClickOnce 部署的并且需要自己检查和下载更新。它会在应用程序启动时和晚上的预定时间检查更新。当它在启动时运行时，它运行得非常好。

但是，当它在预定时间执行此操作时，它会崩溃。在这两种情况下，它都使用完全相同的代码。它在 Windows 7 下运行，可能与 UAC 有关.我在想，当计算机处于空闲状态时，它可能无法访问文件系统？我真的需要解决这个问题。以下是异常详情:

信息:

A privilege that the service requires to function properly does not exist in the service account configuration. You may use the Services Microsoft Management Console (MMC) snap-in (services.msc) and the Local Security Settings MMC snap-in (secpol.msc) to view the service configuration and the account configuration. (Exception from HRESULT: 0x80070511)

编辑:我认为原因可能是硬盘驱动器在系统空闲一段时间后关闭。在检查更新(使用 C#)之前，有没有办法以编程方式打开硬盘驱动器？

我会把这个链接放在这里只是为了记录:link to MSDN forum .根据它，这是 ClickOnce 内部的一个错误，导致在调用 CheckForDetailedUpdate() 函数一定次数后出现此错误。
