Re: LabView 7.1 and MATLAB 7 #3
LabVIEW 7.1.1 was released around December of 2004, however, if you purchased a new seat of LabVIEW in March 2005, you still would have only received LabVIEW 7.1. The 7.1.1 maintenance release was distributed only as a downloadable update to LabVIEW 7.1, not as a full product installer.
You can verify which version of LabVIEW you have by selecting "About LabVIEW..." from the Help menu in LabVIEW. Near the lower-right corner of the window that comes up it should show you the version number, i.e. 7.1 or 7.1.1.Message Edited by Jeff B on 04-20-2006 11:30 AM
Actually we are facing the same problem initially after installing the LV8, but the problem is that the script you have written in the LV and MATLAB are not matching there will be a mess of variables, which you have written, and it says that it couldnt take the data into your script of LV from the original script or either it could not connect to the MATLAB, it is a necessary that while you are running a MATLAB script in the LV, your MATLAB script must remain open.
...Re: LabView 7.1 and MATLAB 7 #2
And I'm sorry that the link I posted 1.5 years ago didn't survive the discussion forum migration.
But I will say that the 7.1.1 maintenance release included all fixes for LabVIEW 7.1, including some with the MATLAB script node. This is a free download avaliable here:

The KB entry Kileen linked above has more information about this, including a link to 7.1.1, but all you should really need is to install 7.1.1.
...Is LabVIEW 7.1 Aug2005 identical to LabView 7.1 May2005?
I am attempting to have a coworker at a remote site set up their PC with the exact same software as one that I have here. I used the August 2005 CDs from Developer Suite. My coworker tells me that he has the TestStand 3.1, and the Device Driver CDs from the Aug2005 Dev Suite shipment, but he can only find LabView 7.1 from the May2005 delivery.
I would like to safely assume that LabView 7.1 is LabView 7.1, regardless of whether it was shipped in May or August, but it is really important to me to make absolutely sure that we end up with the same software versions. So I was hoping somebody could confirm that the May and August CDs (Dev Suite, 2005) contain the exact same LabView software version.
I noticed that there were 3 LabView 7.x version selections for submitting this issue; 7.0 7.1 and 7.1.1
I set up my PC using Aug2005 CDs and my LabView splash screen shows "7.1". Can I assume that if I had version 7.1.1 that I would see "7.1.1" on the splash screen? (Many pieces of software do not show the 2nd decimal point or anything past it on their splash screen. The Help | About selection for LabView just ends up showing the splash screen again.)
My Aug2005 CD shows "7.1" printed on it. Can I assume that my LabView CD would have &quo...LabView 7.1 and MATLAB 7

...Labview 7.1 and Matlab 7.4
We had a vi working with Labview 7.1 : Unfortunately University upgraded the common version of Matlab to 7.4(R2007a) from 7.2 - and - the vi stopped working - no error messages while running the vi.
1. does Labview 7.1 support Matlab 7.4.0
2. Is there any patch DLL etc to resolve the problem?
Thanks for your help.
When running that script, I got my Labview to communicate with the Matlab server - as he explains -
it launches the local copy of Labview within the SoftGrid environment and that would allow it to interact with Matlab.
I can send the OSD file to you. The only problem is while in the middle of the analysis, it crashes sometimes because it forces Matlab to open too.
I am in touch with computer centre to resolve the problem.

I just installed LV7.1 on a new machine and I'm developing source code
for a customer with LV7.0. When I tried to save the vi in LV7.0, I got
several messages that said certain components could not be saved in
7.0. But a vi WAS saved along with a directory containing some support
files. I have two questions: (1) Will these files work on 7.0 (I'm
assuming no) and (2) is there any problem with installing 7.0 after
installing 7.1 (separate coexisting systems).
You should be able to install LabVIEW 7.0 after LabVIEW 7.1. I
typically have at least the three last version installed concurrently.
Do you have more details on the error messages? Many times you can
ignore them, e.g. it won't convert any system VIs from vi.lib because
it will use the ones from the 7.0 installation.
Of course if you use a new 7.1 feature that is not available in 7.0,
it will still convert, but you might get a broken VI with the
incompatible elements missing. Simply open the broken VI in 7.0 and
program around the problem areas.

...Co-existing Labview 7.0 and 7.1
I have Labview 7.0 running on a Windows 98 OS. There are VIs written in this environment that I do not want to lose. Can I install Labview 7.1 while keeping the Labivew 7.0 as is? Later, if my existing programs still work OK (i.e. if I do not detect any forward compatibility issues), then I might uninstall 7.0. Thanks in advance.
You can have many co-existing versions happily residing on the same PC.
I forgot to mention one thing.
You simply have to be careful not to open a VI created by an older version with a newer version of LV because it will save it in the newer version. Unless yo do want to bring up the version of the vi.
In other words, if you have a VI created in LV 7.0 and you have multiple versions installed; then you wish to open the LV7.0 vi but keep it as a LV7.0 vi; right click and use Open With and select LV7.0. You can open it with any newer version as long as you do not save it because it will save it to that newer version. However, opening it with LV7.0 and saving it will preserve it to LV7.0.
Other suggestion: keep a backup copy of your work ;)
Heed Ray's warning. When you go to open a VI in LV7.1, it WILL NOT warn you that the VI was created in 7.0. It is easy to forget which version you wanted to maintain an application in if you have a need to maintain them in the original versions.
7.1 will not run on Windows 98.
Good catch ts...labview 7.1 to Labview 8.0 upgrade
My company has recently aquired labview 8.0 licences and is intending to use it as its development platform instead of labview 7.1. the problem is that all of our customers are currently running executables generated in a labview 7.1 environment and any updated versions of our software that we will send them in the future will most likely be developed in labview 8.0. The question is , other than sending them the executables generated by LV8 along with LV8 RTE are there any problems. did any one see a problem with a conversion like this. i have done alot of reasearch about this and have been testing the converted code from 7.1 to 8 and the executalbes generated by 8.0 and i havent seen any major problems. any feedback on a related probelm would be greatly appreciated.
