database connection Access 2007 and Access 2003

Question

hello, I developed an application with Visual Studio in C # and I use the datasource for a control connection to the database Access 2007 after I finish I programmed the application when I test it on another computer it does not work becaufe this machine installs only access in 2003.

that's what I can do to solve this problem and put this application running on access 2003 returns to zero and redo all the work with a database 2003 or what?
