How to recover VI if it is saved by higher version accidently

[ATElearner]

Is there a way can recover the VI to 6.o if it is opened once by 7.1 and maybe saved accidently?

Not unless you also have LabVIEW 7.0 and 6.1. LabVIEW has the ability to save to the previous version. With 7.1, you can save to 7.0. With 7.0 you can save to 6.1. And, finally with 6.1, you can save back to 6.0. If you don't have all of ther versions, you can post the VI and ask someone here to do the conversion for you.

This is a good illustration of the need to use Source Code Control, or some other backup mechanism, so that you're not screwed if you accidentally do something catastrophic to your VI.

That sounds like a plan.

so is there any other version between 7.1 and 6.1 except for 7.0?

Thanks alot

Hi ATELearner:

I would also recommend investing in a version control system and using it regularly.  There are plenty of good, free systems available such as CVS and Subversion.  The next time something like this happens, you can roll back to the last good version in the repository.

No, you can convert via the path 7.1 to 7.0 to 6.1 to 6.0.

P.S. - The Save for Previous function in a version of LabVIEW will always save back to the most recent previous major or minor release.

I could not find 7.0. Can I find a temporary one from NI.com? Since I only need if for maybe 5 mins? Thanks.

Hi ATElearner

Is it possible for you to post your code here?  I would be happy to save it back to 6.0 for you.
