Automation Error

[manofprayer]

Can anyone help me with this error?

Class does not support Automation or does not support expected interface.

What does this mean?
What causes it?
What does can I do to remedy this?

What is giving you this error? Post some code if you can.

It is a bit of a generic error and we will need more info for a proper answer.

More, much more data needed...

Well here's the problem:
This problem does not occur while I am testing it (meaning when I run it with a VB Editor, the error does not come) only after I deploy it.

A bigger problem is this:
I don't always get this problem with all the machines I have tried it on. There are 3 to 4 machines where I deployed the program where this problem does not occur. Only 2 machines have this problem (so far).

This is what I know:
I know that Automation Errors occurs in classes and objects right?
My theory is that a 'User Control' that I created is the reason this error occurs. But what I did it is, I did not compile the object as an .OCX, what I did was I included the object as part of the Project so I am assuming this error shouldn't occur. And again I go back to the question why it only happens in isolated cases and not always? Could it be compatibility issues with the OS or the machine?

Any help is greatly appreciated.
