We offer various distributions of our LabJack UD driver, the software layer that communicates with U3, U6, and UE9 devices connected to computers running Microsoft Windows.

• If your version of Windows is 32-bit or 64-bit with 32-bit software (Most common), please install the LabJack UD driver using this installer. This applies to users with Microsoft Windows 2003, 2008, XP, Vista, and 7.

• If your version of Windows is 64-bit and you specifically deploy or use 64-bit software, you will need to use the beta release of our 64-bit driver. Please begin by running the normal LabJackUD installer and then use the provided instructions to configure your machine to use the beta DLL. While this is required for applications intentionally targeting a 64-bit platform, please note that most programs running on a 64-bit machine are still 32-bit applications.

• If you don’t know your system architecture, please see this Microsoft support page.

• If support has asked you to use the beta release, please follow these instructions.

• If you are using Windows 2000, ME, or 98, please install V3.06.

• If you use one of the UD family devices but choose to run Linux or Mac OS, please see our Exodriver page. Also, for software related to the U12, please visit our U12 product page.
