Failed to Load FTD2XX.DLL Error

« Go Back


 After installing the software, if proper drivers were not installed, you will likely see the following error: "Failed to load FTD2XX.DLL".  This guide will help you resolve that issue.
*Note If the OS you're installing on is a VM please make sure the device is added to the guest OS and configured otherwise you may see this same error.

  1. Using the following link, download the appropriate drivers based on your Operating System: D2XX Drivers Download. Windows users should download the "Setup Executable" (Direct Download)
  2. Run the previously downloaded executable.  You may need to right click the file and select "Run as administrator"
  3. Extract and install the drivers
