How to open an older version of a VI?

[MicTomReiSr]

Is there a means of opening an older VI in a newer version of LabView? I get the expected error, "Load Error Code 10" when trying to open a VI saved in version 3.1 with my LV version 7.0 software. There should be a means of doing this, at least in principal.

You need a free conversion kit for VIs older than version 4. For more information, see the post here.
