Is there any way to specify the default version of LabVIEW?

[eaolson]

I have a sinking feeling that the answer to this question is "no."  With more than one version installed, is there any way to set the default LabVIEW version for opening a VI? I have both 7.1 and 8 installed, and usually only use 8 to open an example or look at something posted here.  When I do that, it resets all the OS hooks so that the default action for opening a VI is to open it in version 8.  I've even gone so far as to create actions to open files in 7.1 and 8, but it always resets my default action.

I found this KB article for when version 7 came out, but it's suggestions don't seem to work with 7 and 8.

Ugh. I hate it when software thinks it knows what I want better than I do.

You could try Dataact's version chooser. I haven't tried it myself, so I can't comment on how convenient it is.

Another option is JPD's trick here.

Add in the LabVIEW.ini file of those versions you do not want to rewrite the registry on startup to point to themselves for VI files, the following:

RegisterExtensions=False

Of course the VersionChooser utility mentioned earlier is even more convinient.

Exactly what I was looking for! I knew it had to be there somewhere. I don't suppose these useful little undocumented tweaks are documented anywhere?

The most comprehensive list is in Brian Renken's site.
