I have a a program written in labview 7 which out of the blue has stopped working. An error code now comes up saying it cant find 'check special tags.vi'. and so the program will now not run. I can't find any version of this sub vi for this version.
I have Labview versions 8 and 8.2 but the 'check special tags.vi' will not work in version 7. The problem I have is that I am not a programmer and the rest of the (very complicated) program is written in version 7. I do not have the time or experience to even know where to begin. Can anyone help me trace this sub vi?
Thankyou

Hi ncduser,
Can you please let me know what operating system you are using?
Thanks,

Hi again ncduser,
It may be the case that the check special tags VI has been saved in one of the higher versions of labview. You could try opening the check special tags VI in 8.2 and click "save for previous version", then save it as a labview7 file from there. Make a backup of the file first just incase it doesn't help.
Please let me how you get on.
If this step doesn't help, would be it possible for you to upload the code for me to take a look at?
Thanks,

Hi Stephen,
Sorry for the late reply. That worked so thankyou very much for your help.
You may be able to help with another problem I have, The program collects data but it's not in a readablr format for excell etc, so we have another labview program that opens the data file from the original program and saves it in an excell readable form.
Since fixing the previous problem the second program is now not working as it should (It doesnt save anything other than a file name)
The original program now works in Labview 8.0
The secind program is written in labview 8.2..
But there was never a problem before. Any suggestions? I can send you the code if you like via email.

The NA-QCM-VISA is the program that runs in labview 8.0 and collects data writing to a file.
The 3 QCM fit program is the program that converts the data and saves to a file that can be opened by Excell.
Before the problem with the missing sub vi the program would write to a file ( eg 1650.dat file - attached) which opens succesfully with the QCM fit program
The PVOH file is a file from the collection program since the sub vi was fixed - and will not run on the conversion program.
However since fixing the file from the collection of data saves but does not open up.

Don't start two threads with the same problem.

Please see the following link for the code and post any further comments/suggestions there. Although initally two separate problems, both threads have ended up the same.
