InvalidOperationException when creating PerformanceCounter

Question

i'm trying to get the actual free memory. It seems to be the easiest solution to use Performance Counters. It works totally fine on my Coding Machine, unfortunately I get an Exception on the target Computer. I use Windows XP an .NET 3.5 Can you please help me?

Code:

namespace TestConsole
{
    class Program
    {
        static void Main(string[] args)
        {
            PerformanceCounter ramCounter = new PerformanceCounter("Memory", "Available Bytes");
        }
    }
}

Exception:

Unhandled Exception: System.InvalidOperationException: Category does not exist.
   at System.Diagnostics.PerformanceCounterLib.CounterExists(String machine, String category, String counter)
   at System.Diagnostics.PerformanceCounter.Initialize()
   at System.Diagnostics.PerformanceCounter..ctor(String categoryName, String counterName, String instanceName, Boolean
readOnly)
   at System.Diagnostics.PerformanceCounter..ctor(String categoryName, String counterName)
   at TestConsole.Program.Main(String[] args) in D:\Projektarbeit\Bachelorarbeit\VS2010\Projekte\DiagStationControllerTe
stConsoleV1\TestConsole\Program.cs:line 15

this seems to provide a solution: http://support.microsoft.com/kb/300956/en-us unfortuanly im not allowed to alter the registry on my target — Christian Elsner, Jun 18 '12 at 13:03

Exception message says everything:

Category does not exist.

Mean category "Memory" does not exist.

I could not resolve the underlying issue, but there is a workaround by not using PerformanceCounter, but API-Calls, see http://www.codeproject.com/Articles/1285/Calling-API-functions-using-C
