The Elveflow Smart Interface (ESI) latest version can be downloaded from the Elveflow website.

See how to get the ESI software and the SDK in the animation below.

The archive contains a SDK subfolder for any user looking for building a custom interface.
ESI has to be installed to ensure the availability of every resource required to communicate with the instrument. 

For X64 libraries, LabVIEW X64 Run-time should be installed. It is included in the installation file (Extra Installer for X64 Libraries). 

ESI and SDK documentation are included in the archive file. 

Downlolad and unzip the archive into your computer desktop to access contents and install the files.
