原因是我正在研究一种从本地系统服务调用时运行某些iTunes任务的方法，因此在某种程度上，我正在尝试将调用提升回登录用户。您是从提升的（管理员）PowerShell控制台运行此任务吗？如果我从提升的PowerShell控制台尝试此操作并指定localhost和cred，我就能够启动COM对象（我尝试的就是Excel.Application）。顺便说一句，这是在加入域的系统还是家庭/工作组PC上？嗨@keith hill，它以我自己的身份运行，我是这台机器上的本地管理员，但我没有专门设置任何东西使powershell以管理员的身份运行。我在家里和工作电脑上都试过，一台是独立电脑，另一台是网络电脑，但两者的连接问题都是一样的。但是，这样运行时，替换iTunes for Excel，COM对象将连接。看起来它可能特定于iTunes？我将Powershell设置为以管理员身份运行，方法是：右键单击Powershell，选择快捷方式选项卡，单击高级按钮，选择以管理员身份运行。再次尝试调出iTunes COM对象，但出现相同错误。我想知道它是否真的在完成之前超时了？它似乎思考了很长一段时间，但如果您放弃凭证，它会相当快。
