c# - ClickOnce 无法运行 - 获取 'Specified Cast Not Valid'

Question

我有一个 C# 应用程序，我们在 Win7 机器上部署(使用 ClickOnce)没有任何问题(多年来)，但我们有一些员工使用 Surface Pro 2 (8.1)，并且该应用程序无法安装。当他们运行 setup.exe 时，他们会收到标准的“请联系您的管理员了解详细信息”错误。这是它生成的日志:

我看到它说“Specified Cast is not Valid”，但我不太确定为什么会出现该错误。到目前为止，我已经尝试了以下方法(没有运气):

1. 将 objective-c PU 从 x86 更改为任何 CPU
2. 将签名从 sha1RSA 更改为 sha256RSA
3. 以管理员身份运行 setup.exe
4. 关闭所有 UAC
5. 创建了一个基本的 Windows 窗体(1 个窗体，1 个按钮)并尝试安装，但出现同样的错误。
6. 最新 - 我从基本的 Windows 窗体应用程序中获取了 .exe，并在 Surface Pro 上运行它，它运行良好，所以我认为这一定是设置问题。<

在这一点上，我认为这是我缺少的 Surface Pro 或 VS 部署设置的设置。

非常感谢任何想法或建议!

这是由于用户安全设置引起的。

如果您选择它，如图所示，问题会自动解决。您可以继续安装。

如果您看不到上面链接中的图片；

打开控制面板 -> 用户帐户控制设置

调整从顶部数第二个 slider 。 (仅当应用程序尝试更改我的计算机时通知我(默认)
