We have got a ‘live’ dnn 9.13.2 installation with 2sxc 17.9 which is working without problems. I made a copy of this installation to use as a local dev environment.
And when I try to login on this environment I get an error. I think it might be related to the skin which is based on 2shine:

DotNetNuke.Web.DependencyInjectionInitialize - Unable to configure services for ToSic.Sxc.Dnn.StartUp.StartupDnn9, see exception for details
System.IO.FileNotFoundException: Could not load file or assembly 'ToSic.Sxc.Code.Generate, Version=17.9.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Het systeem kan het opgegeven bestand niet vinden.

Any idea why the live site does not have a problem, while the dev environment doesn’t?

I’ve checked the bin folder, but there is no difference between live and dev. So a missing file does not seem the problem.

Also tried to set the rights in IIS again, but that does not seem to be the problem.

What am I missing?
