The DownloadManager.VerifyRequestedPrivilegesSupport method is throwing an InvalidCastException. Unfortunately, the code for that class is not available on ReferenceSource, but when System.Deployment.dll is decompiled, the culprit is clear. The decompiled method looks like this:

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]));
}

The line that throws the exception would be this one:

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

The code reads registry key \HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersio‌​n\Policies\System from the windows registry. For it to throw that exception, the key must exist and it must have an EnableLUA value, but the value must be typed as something other than an integer. You need to run RegEdit.exe on the machine that's getting the error, navigate to that key in the registry, and inspect that value to see what it is. It should show REG_DWORD in the Type column for that value. If not, delete it and re-add it with the right type.
