I have a package that I developed in VS2012 (using the SQL Data Tools component) which collects data from a DBF file using the VFPOLEDB provider, and puts it into a database on a SQL Server 2012 X64 server. The project containing the package has the DebugOption of Run64BitRuntime set to false. I have imported this package to the SSIS Package Store of a test and live server (identical setups).
