I'm not sure I understand your question.
When are you copying the VI? During Runtime?
Are you calling it dynamically at all?
In the Paths page of the Options menu you can define Constant paths to search in and relative paths, but you should consider the fact that if the VI isn't found where it's supposed to be, it will take a while before it's found.
If this didn't help, please post more details about what you're trying to do, preferably with an example VI.
