Driver for Windows 8 / Windows 7 / Windows XP / Windows Vista (as a setup executable) This is a single driver for both 32 bit and 64 bit Windows versions. Download the file to a folder of your choice and double-click on setup.exe to install the drivers.

If you are using 64 bit versions of Windows XP/Vista/7 and are experiencing problems recognizing the load cells/interfaces, please reinstall the drivers and make sure COM ports are assigned and show up in the device manager.

Drivers for other operating systems, including Windows CE, Linux and Mac OS are available here.

Some earlier models of iLoad digital USB load cells shipped prior to 2009 need a driver (from Microchip Corporation) that is available here. This driver is compatible with Windows XP 32 bit and Windows Vista 32 bit computers only. It is not compatible with 64 bit versions of Windows XP, Vista or any version of Windows 7. (If you have any of these load cells, please contact sales to purchase newer versions at a discounted price).

Simply download the zip file and extract the contents to a separate folder. When the load cell is connected, Windows will ask for the driver. Simply point to the .INF file in this folder.
