error instaling LabjackUD

When I try install labjackud, the program show me "The LabJackUD Setup Wizard ended prematurely" and uninstall all.

I am using Windows Vista. What can I do?

Troubleshooting the UD Installer

If you are using the installer from the CD, you might try using the one from our website.  Another fix that often works with Vista is to right click the installer and select "Run as administrator" option.

If none of that works you can run the installer from the command prompt (Start Menu -> run -> cmd) and create a logfile using:

C:\LabJackUDSetupV315.exe /L*V "C:\LJInstaller.log"

You will need to use the name of your installer in place of the one above (3.15 is the most current) and you can rename the log file if you wish.  This works assuming the installer and log file will both be in the root directory on the C: drive.  Once that is done you can email us the log at support@labjack.com and we can take a look and see what is failing.

2 labjacks

can i hook more than one labjack up to one computer at the same time and reference both of them in the same program??

Yes

Yes.  Some of our simple sample applications are just set up to talk to 1 device, but in general you can connect lots of devices.  In software you address them by serial number or a Local ID (0-255) that you specify.

What about mixing U12 and U3 on one machine?

In looking at the labjackusb driver there is no u12.h equivalent file so that I can access the U12 labjack with the same functions as I do for the U3. My program functions under Linux. I have the labjack kernel module installed for the U12 and I'm wondering if I can have both labjacks installed on the machine at the same time. How do I tell programatically what one is which? I suppose InitLabjack() should only get the first U12 labjack, right? openUSBConnection() (referenced from the u3.c/.h helper functions) should only return the U3 ID, yes?

 

Yes

Yes, you can use a U3 and a U12 at the same time.

You can see in the code for openUSBConnection() in u3.c that it will open only U3s.

The Exodriver (new Linux driver) has preliminary support for the U12, but we don't have examples or a u12.h file. I would keep using the old kernel module code for it if it's working for you.
