Thanks Thibaut, I tried that, and get the same error. Maybe I should try  
out  
older binaries.

Apart from that, I want to make sure, that my approach to embedding  
IronRuby  
in a .NET app is right (didn’t find any tutorials on embedding):

1. Add references to IronRuby.dll, IronRuby.Libraries.dll,  
Microsoft.Scripting.dll and Microsoft.Scripting.Core.dll
2. Create a engine like this

var engine = IronRuby.Ruby.CreateEngine();

and then executie ruby code on the engine itself with Execute, or  
compile  
code into a ScriptSource and execute that.  
Are there any steps missing? ir.exe has a config file. I don’t need one  
to  
get iron ruby basically running, do I?  
The standard library is embedded in IronRuby.Libraries.dll, so I don’t  
need  
to set a load path, right?

I would be willing to write a tutorial on embedding once I got  
everything  
together and working.

Thanks for clarification,
