I think that Micah's problem should be discussed with attention, leaving the "support" question on the side.
Most programmming languages are text-based. So you can open a source with any text-editor, and have access to the program. Often, after minor modifications, you can even recompile the source not only in an older version, but also in another language.
In contrast, with LabVIEW, you cannot open a vi written in a newer version, even if the program consists in a single simple addition. When working with an up-to-date version, you cannot save your work in a previous version, except for the very last one.
I have been using LV since version 2.2 and each update has been the occasion for anger and desperation, each time I forgot, for one reason or the other, that all the computers I was working with were not loaded with the same version.
I tend to believe that version compatibility is not only a technical problem, and I would really be happy to get a convincing explanation of the impossibility of converting a vi from LV 7.1 down to LV 6.
Just my 2 cents of criticism...
