AttachProfiler failed: 80070002 when attempting to load the profiler for ASP.NET service hosted on IIS.

I am using Yourkit .NET Profiler 2022.3-b106. The ASP.NET service (64-bit process) is using .NET CLR Version v4.0.30319 hosted on IIS on Windows Server 2016 Datacenter operating system.

I tried multiple options to confirm if it is an access issue, but it is not. I am an administrator on the server. Also, I ensured that no other profiler is running on the server.

Please try the latest version 2022.9. Most propably the problem is already resolved.

Did you try to run profiler "as administrator" from Windows before attach?

For your information, it is possible to directly integrate with IIS to profile ASP.NET applications: https://www.yourkit.com/docs/dotnet-pro ... al_iis.jsp

IIS profiling can be also enabled by command line:

Code: Select all

<Profiler Installation Directory>\bin\YourKitTools.bat iis-enable

IIS integration is a preferred method over attach, because attach has some limitations.
