Access is denied when loading assembly in new domain

[Casper Hornstrup]

I try to load an assembly in a new domain, but I get an FileLoadException.
I've given all rights to Everyone on the bin directory and below. What could
I be missing?

Relevant code:

Loader loader = new Loader();
loader.LoadAssembly(@"c:\inetpub\wwwroot\ch\ObjectTree\ObjectTreeWS\bin\Demo
1.dll");

Constructor for Loader class:

public Loader()
{
AppDomainSetup setup = new AppDomainSetup();
setup.ApplicationBase = AppDomain.CurrentDomain.BaseDirectory;
setup.PrivateBinPath = "bin";
setup.ApplicationName = "ObjectTree backend";

appDomain = AppDomain.CreateDomain("ObjectTree backend", null, setup);

remoteLoader = (RemoteLoader)appDomain.CreateInstanceAndUnwrap(
"Demo1",
"ObjectTreeWS.RemoteLoader");
}



System.IO.FileLoadException: Access is denied: 'Demo1'.
File name: "Demo1"
