I add two tables with master-detail relation in DataEnvironment of a form. The two tables and their DBC are in a subdirectory. I build the application, run it. It works fine. But if I move the application along with its subdirectories to another location, I get "Error instantiating cursor object, cannot find (current path)\(dbc file)" when I run it.

What is the cause of the problem? How can I fix the problem using the DataEnvironment? Thanks.
