SLR Booth is a cross-platform application that works on Windows, Mac OSX, and Linux, and it relies on the LibUSB library for cross-platform USB support. While Linux and Mac OSX have LibUSB support built-in, Windows users need to install an additional driver to allow the application to talk to cameras over USB.

Install SLR Booth Pro for Windows by downloading the installer.

Next, Install the required driver.

First, download and run the LibUSB driver installer

When the window opens, choose Options > List All Devices, then choose your camera in the dropdown list
