Please help! unable to add performance counters - 'Add' button is disabled - enterprise-library

Question

I have created performance counters using Entlib 4.1 as below. When I open up the performon.exe and Add Counters - I can see the Performance Object I created, and the list of counters. However I can't add them becuse the Add button is disabled. Any suggessions?
public class Program
{
static void Main(string[] args)
{
Console.WriteLine("You are about to install the performance counters");
InstallPerformaceCounters();
Console.ReadLine();
for (int i = 0; i < 100000; i++)
{
if (i % 3 == 2)
{
Thread.Sleep(100);
}
if (i % 5 == 2)
{
Thread.Sleep(1000);
}
PerformSearch(i);
}
Console.ReadLine();
}
private static void PerformSearch(int i)
{
Console.WriteLine(i);
}
private static void InstallPerformaceCounters()
{
try
{
PerformanceCountersInstaller installer = new PerformanceCountersInstaller(new SystemConfigurationSource());
IDictionary state = new System.Collections.Hashtable();
installer.Context = new InstallContext();
installer.Install(state);
installer.Commit(state);
Console.WriteLine("Performance counters have been successfully installed.");
}
catch (Exception ex)
{
throw ex;
}
}
}

This was my mistake. I need to run the app, particularly the methods that are decorated with those counters, so I could add the counters to the list.
