NI6501 expr vi corrupt on some pcs

[hammer3]

I have a vi that uses the NI 6501 DAQ and I use the Express vi to configure it. It works perfectly, until I try to use it on another pc. On the "other pc" I imported the configuration file for the USB DAQ from the original pc first, then when I open the vi, I get a broken arrow and when I look at the express vi properties, I get the attached message.Even if I delete the USB names from MAX I still get this message when I try to read the express vi properties with no DAQ connected. I can load this vi into other pcs where I did NOT import the config file with no problem. Should I NOT have imported the config file, and if so, how do I get rid of it?

Hi Hammer3,

Just to confirm are you using the steps outlined in the below article: http://digital.ni.com/public.nsf/allkb/42A2D212796B3DC2862571FF0061B402

On your target computer do you have other devices that show in NI-MAX? I ask because when importing the configuration file it will set those configurations to the device with the same name. Example "Dev1”. If you are not using the others devices can you delete them all and then import the configuration file?

When exporting your configuration file, what do you select to be included in the configuration file?

Thank you for your input MJ. NI tech help solved the problem for me. I needed to update DAQmx to 9.8 and the problem went away. It wasn't the config problem I thought it was. I have successfully imported config before, taking into account the things you said. What still puzzles me though is that I have several other pcs with the same DAQmx rev that work fine with this Labview program and device. I will update all the DAQmx's. Thanks again for your input.
