I have been learning LV in 2010, but we still use 8.6 as our main version.
I need to resave a vi from 2010 to 8.6 and can not get it to do so.
Is there some tricks or extra steps I need to do?
I have full versions of both 2010 and 8.6 on my machine.
After resaving inb 8.6 the vi will still only open in 2010.

If you open the down-converted version in 10.0 again, what does it say for "source version" in the VI properties?
What error do you get if you try to open it in 8.6?
OK, I also resaved it under 8.6. See if you can open this one.

When I try to open the file after it has been resaved in 8.6 I get error messages as it is opening such as "Find the VI Named DAQmx Clear Task VI".
This happens several times as it is trying to open in 8.6. Then when it opens none of the DAQ icons are there in the block diagram.
So it seems the bulk of the program was successfully resaved in 8.6, but the DAQ functions were not able to go from LV2010 to LV8.6.
Is there a special fix for resaving the DAQ functions?

You don't resave DAQmx functions. The DAQmx driver needs to be installed.

OK, that is very different than your original description of "After resaving inb 8.6 the vi will still only open in 2010.". Obviously it will open, but with errors. 😄 Follow Dennis's advice!

Actually it does both.
On one computer it would always just try and reopen it in 2010 even after being saved as an 8.6.
If you right clicked on the file name and checked properties, it was still shown as a LV2010 file.
On another computer it does try and open it in 8.6, but doesn't load/open the DAQ functions.

If you click on a VI in explorer and you have multiple versions of LabVIEW installed, it will open in whatever version you used last (it is actually slightly more complicated). If you want to open in a specific version, you need to open that version first and then open the file.
The "properties" dialog in windows explorer will not show the source version, it will just show what program is currently assigned by default to open it. That's not the same.
To check the source version, you need to open the file first, then go to VI properties.

Is the DAQmx driver on the original installation CD?
Is it something I can get off of the NI website?
I am not completely sure what I'm looking for.
Are the DAQmx functions treated like an instrument, thus having it's own driver?

DAQmx comes with the LabVIEW distribution on thr device driver CD/DVD, it comes with each DAQ device, and you can download it

DAQmx is a library that allows you to configure, control, and get data from DAQ devices that NI sells. You should start reading here: Getting Started with NI-DAQmx: Main Page
