Hi Viv,

I have a problem.

Basically, my questions were because we wanted to be able to run our middleware com class in the training mode.

The original code was the following:

public enum ReturnType { UNK, STR, XML, XM2, XM3, DSP, ADO }; // UNK = unknown, if it has not been set or they selected an unavaliable value
    // TODO: Enum of methods - change 

    [Guid("1c3f2f40-86f0-418b-a33f-9bdda89e82b5"), InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]
    public interface IMiddleware
    {
        [DispId(1)]
        String Invoke(String input);        
    }

    [Guid("362941ee-ae94-41a2-9dd4-3e159e87cb4d"), ClassInterface(ClassInterfaceType.None)]
    [ProgId("Siriusware.Middleware")]
    public class MiddlewareCom : IMiddleware
...

It worked fine.

I added a new class and also generated a new GUID using the Tools/Create Guild so the signature now is the following:

//[Guid("BCD1A253-6D2F-4BBF-9164-184AF7B7414E"), ClassInterface(ClassInterfaceType.None)]
    //[ProgId("Siriusware.MiddlewareTraining")]
    //public class MiddlewareComTraining : MiddlewareCom
    //{
    //    public MiddlewareComTraining() : base("Training")
    //    {
                        
    //    }
    //}

I added running this class as a service using our PoolService program (written in C++).

And now I am able to run the training service fine, but I can not run the Live service anymore.

The pool log has the following

2017.07.07 18:26:11.341 ( 1 ) Unable to Create Instance of Siriusware.Middleware Error: Unable to load Siriusware.Middleware. Invalid class string
2017.07.07 18:26:11.341 ( 1 ) Unable to load Siriusware.Middleware. Invalid class string

Even after I commented out the training class and re-tried I still can not start the service.

So, do you know what may be wrong?

Thanks in advance.
