You can save 8.2 VI's into 8.0 VI's by going to the File menu and selecting "Save for previous version". If you need to save for a version before 8.0, you will need to open your newly saved VI in LabVIEW 8.0 and do the same thing for 7.1.
I think the user is asking for the 8.0 version because they only have 8.0 and someone gave him the VI as 8.2. You can ask the person who gave it to you to convert it 8.0, or here it is in 8.0..
