Hi, I am trying to install APM on a .net application using the Profiling Auto instrumentation method according to the following document: [Profiler Auto instrumentation | APM .NET Agent Reference [1.x] | Elastic](https://www.elastic.co/guide/en/apm/agent/dotnet/current/setup-auto-instrumentation.html)

I have set the path according to the documentation as follows:

When I try to run the application there is an error like the following:

> Exception: System.PlatformNotSupportedException: Performance Counters are not supported on this platform.  
> at System.Diagnostics.PerformanceCounter..ctor(String categoryName, String counterName, String instanceName)  
> at Elastic.Apm.Metrics.MetricsProvider.SystemTotalCpuProvider.GetSamples() in C:\Users\jenkins\workspace\net\_apm-agent-dotnet-mbp\_v1.20.0\apm-agent-dotnet\src\Elastic.Apm\Metrics\MetricsProvider\SystemTotalCpuProvider.cs:line 109

Did you also set the core configurationd

```auto
ELASTIC_APM_SERVER_URL
ELASTIC_APM_SECRET_TOKEN
ELASTIC_APM_SERVICE_NAME

```
