Invalid namespace error on system.management

WMI

I have a program that will query for the state of BizTalk resources, specifically the ReceiveLocations component. When i run the sample program obtained from

C:\Program Files (x86)\Microsoft BizTalk Server 2013 R2\SDK\Samples\Admin\WMI\Enumerate Receive Locations

i get error Invalid Namespace on the line :

ManagementObjectCollection QueryCol = Searcher.Get();

with stack trace :

at System.Management.ThreadDispatch.Start()
  at System.Management.ManagementScope.Initialize()
  at System.Management.ManagementObjectSearcher.Initialize()
  at System.Management.ManagementObjectSearcher.Get()
  at Microsoft.Samples.BizTalk.WmiAdmin.EnumerateWMIClasses.Main(String[] args) in C:\Users\tshumae.FBC\Desktop\BIZTALK\CSharp\EnumRLs.cs:line 114

This is the full program :

<pre>[STAThread]
		static void Main(string[] args)
		{
			// Display help information 
			if (args.Length > 0)
			{
					if (args[0] == "/?") 
					{
						....
						....
					}
			}

			try 
			{	
				//Create the WMI search object.
				ManagementObjectSearcher Searcher = new ManagementObjectSearcher();

				// create the scope node so we can set the WMI root node correctly.
				ManagementScope Scope = new ManagementScope("root\\"+server+"");
				Searcher.Scope = Scope;
			
				// Build a Query to enumerate the MSBTS_ReceiveLocation instances if an argument
				// is supplied use it to select only the matching RL.
				SelectQuery Query = new SelectQuery(); 
				if (args.Length == 0) 
					Query.QueryString="SELECT * FROM MSBTS_ReceiveLocation";
				else
					Query.QueryString="SELECT * FROM MSBTS_ReceiveLocation WHERE Name = '" + args[0] + "'";

				// Set the query for the searcher.
				Searcher.Query = Query;

				// Execute the query and determine if any results were obtained.
				ManagementObjectCollection QueryCol = Searcher.Get();

				// Use a bool to tell if we enter the for loop
				// below because Count property is not supported
				bool ReceiveLocationFound = false;

				// Enumerate all properties.
				foreach (ManagementBaseObject envVar in QueryCol)
				{
					// There is at least one Receive Location
					ReceiveLocationFound = true;

					Console.WriteLine("**************************************************");
					Console.WriteLine("Receive Location:  {0}", envVar["Name"]);
					Console.WriteLine("**************************************************");

					PropertyDataCollection envVarProperties = envVar.Properties;
					Console.WriteLine("Output in the form of: Property: {Value}");
				
					foreach (PropertyData envVarProperty in envVarProperties) 
					{					
						Console.WriteLine(envVarProperty.Name+ ":\t" + envVarProperty.Value);
					}
				}
					
				if (!ReceiveLocationFound) 
				{
					Console.WriteLine("No receive locations found matching the specified name.");
				} 
			}

			catch(Exception excep)
			{
				Console.WriteLine(excep.ToString());
			}
			
			Console.WriteLine("\r\n\r\nPress Enter to continue...");
			Console.Read();
		}

What am i missing? Is there anything specific i need to configure to query BizTalk resources beyond the System.Management namespace or its an issue with the sample code itself?

What I have tried:

I have tried using the code in a separate MVC application where WMI queries are working but i get the same error. The WMI queries in the MVC application are however for querying remote server disk statistics and not BizTalk Server services.
