Loading profiler failed.  The profiler COM object was instantiated, but the profiler does not support attaching to a live process.  The profiler must be loaded at application startup by using a launcher program included with the profiler (if any) or by setting the COR_ENABLE_PROFILING and COR_PROFILER environment variables before launching the application to be profiled.  Profiler CLSID: '%s'
