Building an application that uses Daq-mx cards

[Xavier Pajona]

hi,
I'm using Labviex 7.1 to develop an apllication that uses a couple of  Daq-mx cards as well as a few RF instruments.  The  2 cards are  for the moment in the computer  I use to develop my application. My problem is that when the application will be over, i have to remove Labview from the computer to let the License free. That's why i used the application builder to make a .exe with my app. The .exe file works without problems on the computer with labview. I then installed Labview runtime 7.1.1 on an other computer to try my app on a computer where labview is not installed but this time it doesn't work as a lot (more than a dozen) of DLL seem to be missing, almost all the library that deal with the Daq-mx.
Do I have to install the cards on the computer on wich i want to test the application ? Or maybe only the drivers of the cards ? Maybe some of you have already faced this problem and can help me ^^
Thank you in advance and see you soon in the forum

P.S. It's gonna be quite hard to show youthe program as the computer I use to develop is not connected to the network

This may not help the issue you are having, but starting with NI-DAQ 7.4 you can simulate many of National Instruments' DAQ, tell Measurement and Automation Explorer ("MAX") that they are installed. This has solved some of my "develop on one machine, deploy on another" problems, which as a consultant seems to happen a lot.

P.M.

You should be able to install the daq software and hardware on a computer prior to installing the built application.  I think that the dlls (daqMX stuff) are installed with the driver software MAX that come with the hardware.  after you get the hardware running under MAX, try installing the built .exe and runtime engine, hope it works.  Good luck.  As for license you should check with NI.

You have to always install hardware drivers on any pc which will use DAQ hardware. The default installer for your app does not include them. If your RF instruments are GPIB, then you also need to install NI-GPIB and probably VISA. If your talks to the instruments, then you need the hardware as well. DAQmx now supports USB DAQ and does have a simulation mode but it will only return a sine wave. If you are using IVI for the RF instruments, there is a simulation mode available. Otherwise, you would need thpse instruments as well.

Thanks a lot for your answers, I'll try all this today, hope it is gonna work ^^
