LabJack UD Setup V3.25
This is the installation for the Windows UD driver. This driver supports the U3, U6, and UE9. This install includes drivers, documentation, and the utility applications LJControlPanel and LJSelfUpgrade. Jan 12, 2011, 39.7 MB, Windows XP/Vista/7 32-bit.
The utility applications LJControlPanel and LJSelfUpgrade require the .NET framework available for free from Microsoft.
If you need a different version of the UD driver or use 64-bit architecture, please visit this support page.
If you have a previous version of the Windows UD driver you will need to uninstall it before running this version. Also, if you had LabJacks connected to the system previously and have them connected while installing, you might need to reconnect them before they will work properly.
Note: The UD driver must be uninstalled before this installer will run. The 2 normal ways of doing that are:
- Do Start=>Programs=>LabJack=>Uninstall.
- Go to Windows Control Panel (not LJControlPanel), then go to Add/Remove Programs, then find "LabJack" or "LabJackUD".
If those normal uninstall methods are not available or don't work, here are the manual steps:
- Go to Start=>Programs, find the LabJack group, right-click on it, and delete from the start menu.
- On your hard drive delete the LabJack folder which is usually in c:\program files\.
- Find and delete delete labjackud.dll. It would be in your system directory (e.g. C:\windows\system32).

Just wanted to thank you guys for making it so easy to use Matlab to control our U3-HV DAQ device. [...] You guys certainly made interfacing with Matlab a pain free experience.

I tried to download the installer, and my virus scan (McCaffee) blocks the download, saying that a virus was detected within !
It appears to be a Trojan, named Artemis, located at LabJackUDSetupV325.exe.part\32.nsis.
Could you verify your archive, and confirm to us it is virus free ?
Regards,
Pascal.

This kind of thing happens from time to time. The virus scans update definitions which tag some part of an existing file as a 'false positive.' The file isn't actually infected but some random array of bytes in the file triggers a flag on an updated definition.
We check these files with multiple virus scans to make sure they are clean. I just downloaded this version and compared it to the one we originally uploaded to make sure it wasn't tampered with and found it to be to be the same.
You can check the file you have to make sure something on your end isn't infecting it as it's downloaded in the same way. We use an MD5sum calculation. There are easy to find free tools online you can use to do this. The MD5 for the 3.25 version of this installer if it hasn't been tampered with should be f7a3df06dde26cc1ee6dad385fc1763a. We tested it with MD5sums 1.2 freeware.
These usually go away by themselves, but if that isn't the case and it prevents you from using the file let us know and we can contact McCaffee and have them white list our .exe so it is no longer flagged as a false positive.

What has changed from 3.15????? i.e., Revision history.
#4
There is a revision history found in the LabJackUD.h file in the drivers folder. We are working on putting this online as well.
Almost all the changes were bug fixes and normalizing features so the U3/U6/UE9 all work the same way (when the hardware supports the same functionality). There was also a GetThreadID function added which users can call from multi-threaded applications to help debug issues (since each thread has it's own queue that requests from AddRequest calls go into and execute from).
#5
Any news on when the driver only installer will be released? And also, will it be 32- and 64-bit?
Cheers.
#6
We are just putting on the final touches and should have it up this week. It will be 32-bit and 64-bit.
#7
Great, look forward to it. What format will it come in? Exe or Inf? Could I put a request in for INF as that way I will be able to include it with my software installation.
Cheers.
#8
We have a version up here. This version is a .exe and only supports 32-bit, but 64-bit support will be included in the next release (which should be shortly).
The installer has to do a lot of checks and installs various kinds of different components, thus it is included as a .exe instead of a .inf. Most installer programs should be able to call a .exe from the installer though. If you need help with this let us know.

I just bought a LabJack U3 today but unable to install the drivers in Windows XP. I have admin rights in my PC.
I downloaded the driver, LabJackUDSetupV315.exe and install it in my PC. Afterwards I connect the LabJack to my PC. I selected the install the software drivers automatically in the hardware wizard but instead I get the following message " Cannot install this hardware".
I have also downloaded the beta drivers and copied to system32 folder. Afterwards I connected the LabJack but instead I still get the same message.
Please can you give me a solution to resolve this problem.
#10
The first option is to try and force Windows to install the correct driver. To do this, rather than telling the New Hardware Wizard to automatically install them, instead specify a location. Point it to C:\Program Files\LabJack\Drivers\Install\LabJackx86 and it should find the .inf and start installing.
If that still doesn't work, there are two log files we can look at. There should be a file called setupapi.log created in the windows directory. There should also be one in C:\windows\temp called winusb_update.log. Can you send us both of those to support@labjack.com? I can take a look at them and see what Windows is complaining about and hopefully provide a fix.
#11
I had a similar problem. Then I installed the previous version of LabJack 3.06, and it installed without any problems
#12
I downloaded LabJackUDSetupv315.exe which allegedly supports Windows 7 32 bit. I get the following error message when I try to install:
LabJackUD can not be installed on systems earlier than Windows XP/Vista/Windows7 x64
#13
That error message sounds like the error our installer program typically generates when trying to run the 32-bit installer on a 64-bit version of Windows. Can you double check that it's the 32-bit version? The easiest way to do that is to right click on "my computer" and click on system properties.
If that is the case, this link should work: http://labjack.com/support/ud/ud-setup-64-bit

Is there any way of installing only the drivers, so the documentation, the LJControlPanel and the LJSelfUpgrade are not installed?
Thanks
#15
We have had several requests for this and are including a drivers only version of the installer in the next update we do, which should be soon.
#16
Do you have a release data for this driver only installer yet?
thanks
#17
We are putting the finishing touches on this release. It's going to contain a fair amount of changes/features compared to previous releases. We are hoping to have it out in a week or two.
#18
Any update on that driver-only release?
#19
That version is available and can be found here.
