I installed labVIEW version 8.2 on my computer planning to upgrade from 6.1. I saved many VIs in 8.2 but would like to revert back to 6.1 because of a detector that I use. Is there any way to revert v. 8.2 VIs back to v. 6.1?

Next time you post, please put a short title, like Revert to Older Version, and put the details in the body of the post.

To answer your question, reverting from 8.2 to 6.1 would require all the Labview versions in between.  LV allows reverting to only one preceding level.

So you would have to open in 8.2, and save for previous version, 8.0

Then open in 8.0 and save to 7.1.  Then open in 7.1 and save to 7.0  Then open in 7.0 and save to 6.1.

As a general rule, always make a backup copy of the older versions vi's before converting them to a newer version.

It probably would have been better if you used a shorter subject and put your question into the body of the message.

In order to revert back to 6.1, you will need to install LV 8.0, 7.1, and 7.0 and save back to a previous version.  In 8.2 saveas as 8.0.  Open it in 8.0 and save to 7.1.  Open in 7.1 save to 7.0.  Open in 7.0 save as 6.1.  It's a lot of steps and possibly one of those steps may not be needed.

If it's only a few VI's, perhaps someone with a lot of different versions may be able to do the backsaving for you and you can post them in the message thread.

Whenever doing an upgrade, and going from 6.1 to 8.2 is a MAJOR upgrade, it is always a good idea to backup all of your codebase and store the files away in a safe place.  That way you can open them up in the older version if you need to.  It is much easier to upgrade than it is to backsave.  The reason for storing files in a safe place that if opening up one VI in a newer version calls older VI's in libraries and other parts of your harddrive, it will upgrade all of them as well, and if you do a Saveall when closing your VI, all of those upgraded sub-VI's will then be saved in the new version.

Edit:  Hi Tbob, you must have been just finishing your message and submitted it right after I started writing mine.  I'm glad we were sayint the same thing.
