Hi,I am new to LabVEW software. I am working to design a Lock-In amplifier in LabVIEW. I have downloaded NI Lock-In start-up kit and tried to run in LabVIEW8.5. When the program is loading it is asking to fing some VI's,
"AI Config.vi, AI Read(scaled array).vi, AI Read.vi, AI Clear.vi", which I could'nt locate. Can some one help me with this?. In order to run this simulation do I need any hardware?.
Thank you,Hari.

Those VI's are part of the traditional DAQ drivers. Only the DAQmx drivers are installed because they are the latest/greatest that you should try to use.
What you will need to do is reinstall from the Device Driver CD or DVD and select traditional DAQ support.

The latest version of DAQmx can be downloaded from here. There is a built-in simulation capability with DAQmx and Measurement & Automation Explorer (MAX) which is the configuration utility for NI boards. The simulation is limited to a sine wave for analog inputs and there is no analog output available of course.

Hi there, have you resolve this problem? I am getting the same error, and baffled by the missing subVi. Can anyone tell me where to get those missing files please? I would really appreciate it!!!

Did you download the Traditional DAQ driver as suggested above? When I do that, the Lock-In Demo VI is able to find the VIs that were missing previously.
Also, what version of LabVIEW and Windows are you using?

Hi there, thanks for your reply. I did download the traditional driver, however it still couldn't find those vi files. And I have labview 2011 that runs on windows 7, can they actually cause problems?
Really appreciate your help!

Well, Traditional DAQ doesn't support Windows 7, so I'm suprised you were able to install the Traditional DAQ driver at all. The issue is that the Lock-In start-up kit is several years old and hasn't been updated to use DAQmx.
