安装ClickOnce应用程序时出错

Question

今天我开始每次用户尝试安装应用程序时都会收到错误,我不知道为什么我在部署0个月的问题后得到这个,我没有改变任何与项目属性相关的内容,所有的修改都与代码有关.

这是错误日志

Answer 1

该DownloadManager.VerifyRequestedPrivilegesSupport方法被抛出InvalidCastException.不幸的是,该类的代码是不可用的ReferenceSource,但是当System.Deployment.dll被反编译,罪魁祸首是明确的.反编译的方法如下所示:

private static void VerifyRequestedPrivilegesSupport(string requestedExecutionLevel)
{
  Logger.AddMethodCall("VerifyRequestedPrivilegesSupport(" + requestedExecutionLevel + ") called.");
  if (!PlatformSpecific.OnVistaOrAbove)
    return;
  bool flag = false;
  RegistryKey registryKey = Registry.LocalMachine.OpenSubKey("Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\System");
  if (registryKey != null && registryKey.GetValue("EnableLUA") != null)
  {
    Logger.AddInternalState("LUA policy key = " + registryKey.Name);
    if ((int) registryKey.GetValue("EnableLUA") != 0)
    {
      flag = true;
      Logger.AddInternalState("LUA is enabled.");
    }
  }
  if (flag && (string.Compare(requestedExecutionLevel, "requireAdministrator", StringComparison.OrdinalIgnoreCase) == 0 || string.Compare(requestedExecutionLevel, "highestAvailable", StringComparison.OrdinalIgnoreCase) == 0))
    throw new InvalidDeploymentException(ExceptionTypes.UnsupportedElevetaionRequest, string.Format((IFormatProvider) CultureInfo.CurrentUICulture, Resources.GetString("Ex_ManifestExecutionLevelNotSupported"), new object[0]));
}

抛出异常的行将是这样的:

if ((int) registryKey.GetValue("EnableLUA") != 0)

该代码\HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersio??n\Policies\System从Windows注册表中读取注册表项.为了抛出该异常,密钥必须存在且必须具有EnableLUA值,但该值必须键入除整数之外的值.您需要RegEdit.exe在收到错误的计算机上运行,导航到注册表中的该键,然后检查该值以查看它是什么.它应该REG_DWORD在Type列中显示该值.如果没有,请将其删除并使用正确的类型重新添加.
