I have met this problem before. I solve it in such a way.
(1)in your app.config file, put a placeholder in the connection string. the connection string will contains the file path of the access db file. replace the path with a special string.

(2)when your application start, use Directory.GetCurrentDirectory to get app path. before create a connection, replace the ##path## with the actual path on client computer.

static void test()
{
    string s = ConfigurationManager.ConnectionStrings["test"].ConnectionString;
    s.Replace("##path##", Directory.GetCurrentDirectory());
    OleDbConnection conn = new OleDbConnection(s);
}
