I am equipped with LabView7 and a NI DAQ-Pad 6015 and am trying to monitor temperature using two thermocouples. I have searched for some tutorials online but most suggest using DAQ assistant, which is not listed in the input section of my functions palette. I have downloaded the most recent NI-DAQmx driver which is supposed to be compatible with LabView 7.x. I'm not sure if this means that it is compatible with LabView 7.0. I still do not see the DAQ assistant appear.
Any help or suggestions (about DAQ assistant or how to program in LabView7 to solve my problem) is greatly appreciated!
Thanks.

It's supposed to be. LabVIEW 7 Express was the version that unleashed the evil (for some of us) that is otherwise known as Express VIs (the DAQ Assistant being one of them). Which version of DAQmx did you install? The most recent version is 8.9 I believe, but that does not support 7.0.
EDIT: Traditional DAQ would support LabVIEW 7 and would have the DAQ Assistant, but.... it appears that Traditional DAQ does not support the DAQ Pad 6015.

Yes, I installed 8.9 (as well as 8.6.1 previous to 8.9, which didn't work either) thinking that since it was the newest it would support a broader range of versions, but I guess not.
Do you know which DAQmx version would support Labview 7.0?

It looks like the latest DAQmx version is 8.1 that will work with LV 7.0

I have installed DAQmx 8.1 and now the DAQ assistance appears. However, when I select Analog Input >> Temperature >> Thermocouple and arrive at the physical channels screen, it says "No supported devices found."
I also notice that when I open the Measurement & Automation explorer, it does not appear to detect my DAQ pad, even though the light on it is blinking Ready. A window pops up and says "Can not find RTE directory: C:\Windows\system32\cvirte" followed by "Unable to open c:\program files\national instruments\max\bin\cvirte.rsc". After clicking okay to both windows, I check under Devices and Interfaces to see that my DAQpad 6015 is not listed.
Previously before I had uninstalled everything and reinstalled using DAQmx 8.1 my device was detected, but now it doesn't seem to be detected anymore.
Also, I just realized that while it says everywhere that I have LabView7, when I start the program, the opening window has LabView7 Express written on it. I hope this isn't the cause of all the troubles.

Update:
I have uninstalled everything (and also went in to the Program Files to manually remove any remaining NI folders). I reinstalled LabView 7.0 but did not install the driver CDs that came with it. Instead I then installed DAQmx 8.1.
I no longer get the strange error messages but now I am figuring out how to get the DAQ board detected. According to the DAQmx 8.1 files the 6015 DAQPad should be compatible...

Fixed!
Uninstalled everything-- plus I had to hunt down and manually uninstall some remaining files.
For future reference-- installed labview7 first, but did not install the drivers that came with it. Then I installed the DQmx 8.1. Then used hardware wizard to manually select the driver for the DAQboard.
Thank you all for your help!
