Someone correct me if I'm wrong, but the "library.class" syntax in createobject() is reserved for COM objects - if you're instantiating from your included class, you should have just the class name.

To test that other possibility you only need to try to run your exe on any machine where sqlclss is not registered. Or you can temporarily try to unregister it on your machine. One of those would simulate what I suspect may be the case.
