Should be fine. One thing to be aware of though is that (XP at least) will
load the last used version of labview if you open a vi via Explorer.
Something to bear in mind should you be using the 8.5 version, close it and
then open a 5.2 vi in explorer. 8.5 will open it no problem but do a save
without realising and you'll not be able to open it again in 5.2!

Hi Richard,

you can put the key "RegisterExtensions=False" in the LabView.ini to avoid this behaviour.

I run several versions of Labview (see signature) but only one version is allowed to register extensions (aka to run when opening a vi with explorer) - all other version get this key in the LabView.ini...

What I have done is going into Windows Folder Options->File Types and setup additonal right-click menu items for each version of LabVIEW installed.  So I can right-click on a VI and choose which version of LabVIEW to launch.  I can also set the default option from Open to Open in LabVIEW 8.5, so if I double-click on it, then it always opens in the LabVIEW version I typically use.

Does anyone know if a VI file has a known set of bytes that can be read to know what version of LabVIEW wrote it?  If we knew that, we could make an utility that gets called when opening a VI from a folder.  That utility would then read the byte(s) and then pass the VI on to the appropriate version of LV.  If only a newer LV version is installed, it could optionally be set to warn you that the VI was written with an older version.  Is there a technical reason why this hasn't been done already?

Hi Brad,

"Is there a technical reason why this hasn't been done already?"

Well, no! And it is done already - you just have to search the forum for this tool (I don't have the time to do so at the moment...).

It's called LabVIEW Version Chooser from DataAct.
