Distributed program does not work for USB-8473

[DPearce]

I am using LabWindows 2009. I built a installation program to install my application on another computer. It talks to a couple Agilent devices, a NI USB-6289 and to an in house built controller via CAN using a USB-8473. The USB-8473 is the device I am having the problem. When I run the program in debug mode in LabWindows I communicate through CAN just fine. But when I built my distribution installer and installed the program on another computer it has a problem talking to the USB-8473. I named the USB-8473 CAN0 in Measurement and Automation which is the name I'm using in my program to identify it. But when I try and send a message nothing happens. Usually when I send CAN message a LED blinks on the USB-8473. It is like my program is trying to send a message but it goes to the wrong place.

As a side note I have installed other CVI apps on this computer. They also send CAN messages to this device. When I run these older CVI apps the USB-8473 seems to work just fine. This makes me think I am creating my installer wrong. Deos anyone have any ideas how I can debug this problem?

There is a difference between my installation programs of the old CVI app theat works and the one that does not work. Under "Drivers & Components" of th new CVI app I included "NI-CAN 2.6.3" . In the old CVI app I did not have this box checked. I am not clear on how adding these drivers and components would effect my program, I thought it would only make the installer larger and put more components in the computer getting the installation. I am pretty ignorant on how thes components work and what they actually do.

Please let me know if you have had similar problems.

thanks,

Hi Don,

Have you tried monitoring the CAN bus for data to make sure that it is being properly sent? You can monitor the bus from Measurement & Automation Explorer (MAX). Also, what version of NI-CAN do you have installed on the deployment computer?

Can you run the built executable without creating a distribution? You don't need to create a distribution if the other computer already has all the required support components for you application (for example, the CVI run-time engine, NI-CAN driver).

Were the old CVI applications that do run built in the same version of CVI?

Thanks!
