The visuals were available in MEP 17 and dropped in MEP MX.
They will work in MEP up to MEP 2014 - however you will have to copy the Visuals folder to a folder in your Documents folder and access it through the Media pane.
The 64 bit MEP 2015 and onwards do not accept the .vis file.
Do note that the .vis files are very low resolution and may cause artefact issues when upscaling to HD or greater video resolutions
