Revert to LV 6.1

[mdickerson]

I "upgraded" to LV 7.1 and now all my programs are taking twice as long as before. I'm also having problems with front panel controls working unpredictably. Other people in my company are having a number of other misc. problems. I'm fed up with it and want to revert back to a product that seemed to work for us (LV 6.1). I can revert the development environment, but unfortunately, everything has been recompiled under LV 7.1. Is there any way to revert my programs back? "save with options" doesn't give me 6.1 as an option.....

LabVIEW can only save to the previous version. So you would need to save to 7.0, then open the VI in 7.0 and save to 6.1.

If you don't have 7.0, you may have to contact NI to see if they can help you do a mass down conversion from 7.1 to 6.1. If you only have a few things, you could try posting them here and somebody might do it for you. Or, if there's a lot, and NI isn't willing to help, I'd be more than happy to put together a bid for the work.

On a side note, it's odd that you're having problems with the upgrade to 7.1. I've converted many applications and so far have not really run into any issues. You might want to try working out some of the problems, (we like to help in this area). 7.1 has a lot of new features that you may find useful.

I'd second the other post. Explain what the new problems are. If you
have any windows open that aren't normally open, or haven't saved
things, VIs will run a bit slower. It is also possible that it is a
certa
in driver call or something else.

If you have it, open the Profiler, click start, and run your app to
completion, or at least to a point where you stop it. This will give a
pretty good indication of what is taking the majority of the time.

If you decide to revert and need help, another person you can try to
contact is your local sales rep. This may not be the best introduction
or their favorite visit, but it is worth asking.
