Hi,

How can I export a VI from version 8.2.1 to version 7.0?

Thanks

You'll have to do it in multiple steps. Each version of LabVIEW can save back to a certain subset of previous versions of LabVIEW.

I don't have 8.2.1 open right now, but my guess is that it can only save back to LabVIEW 8.0. So you'd have to save the VI from 8.2.1 -> 8.0, then open it in 8.0 and save it from 8.0 -> 7.1(.1), then open it in 7.1(.1) and save it from 7.1(.1) -> 7.0.

There's an outside shot that you could go all the way from 8.0 to 7.0 in one step, but my recollection is that you can't.

You might be able to work out an arrangement with somebody around here to do it for you if you don't have those intermediate versions and if your project isn't huge.

Before LabVIEW 8.5 LabVIEW only could backsafe one version backwards. 8.5 is the first that can safe two steps backwards (8.2 and 8.0) and according to a presentation I attended at this years LabVIEW User Group they intend to maintain that or even better from now on since they seem to have refactored the versioning of VIs in 8.x in such a way that backsaving to older versions got a lot simpler. Probably also the reason why they removed support for loading 4.x and 5.x VIs in 8.5.
