"Error -10240 occured at AI Group Config" w/ traditional DAQ

[pellet]

I have two DAQ interface installed on my computer, PCI-MIO-16E-4 (Device 1) and PCI-6713 (Device 2). The hardware test was successful. However, when I run my application, to read all 16 channels from Device 1, I got a -10240 error, which corresponds to noDriverError, The driver interface could not locate or open the driver. Could you please give me any suggestions on this?
Thanks.

Which DAQ driver do you currently have installed in your machine? Which LabVIEW version do you have installed? Have you upgraded your LabVIEW or DAQ driver recently? Which operating system do you currently use? The reason I asked these questions is because this error could possibly occur if you have developed your LabVIEW application in an older version of LabVIEW and NI-DAQ driver, a specific file need to be included in your LabVIEW directory (daqdrv file). The link provided descripes the problem and how to go about solving it. If this does not resolve the issue, please post the DAQ driver and LabVIEW versions and I will be more than happy to research this issue further.

Also, in case you have an older DAQ driver installed in your system, it would be a good idea to upgrade to the most recent driver version (NI-DAQ 7.3) which can be downloaded at DAQ Driver

Thanks Ayman, the problem is exactly as you pointed out. After I upgraded my DAQ driver to 7.3, the program works fine. It was written in Labview 5.1, the Daq driver at that time is version 6.6. I upgraded Labview to 7.0, but didn't upgrade the Daq driver when I ran into this problem. Thanks again.

I am glad everything is working great for you now. Good luck with your application.
