Then run it the downloaded .exe application, it will extract itself to a new folder.

Open this folder and then run the display driver uninstaller application within the folder.

The application will open and present the DDU interface.

Ensure that the NVIDIA option is selected in the drop-down menu, an then click Clean and Restart.

The display driver will be completely removed from your PC.

Reboot the PC.

Now, download the latest Nvidia driver for your Rok Box. If you are unsure which GPU you have, you may utilize the Nvidia Experience application to automatically find and download and install your GPU drivers. You may find this application here:
