In labVIEW 6i, you can save your application for a previous version.Go to file>>Save with options>>Save for previous.
Be careful if your application uses some features only available on labVIEW 6i such as polymorphic vi's, waveform datatype..., the conversion will not be succesfull since those features are not available on version 5.
