I'm using the VS solution. It builds without error. However, at runtime it generates this exception:

_ramTotalCounter = new PerformanceCounter("Memory", "Available Bytes");

Exception details are:

System.InvalidOperationException
  HResult=0x80131509
  Message=Could not locate Performance Counter with specified category name 'Memory', counter name 'Available Bytes'.
  Source=System
  StackTrace:

Is anyone else having this problem? How did you resolve it?
