Latest Premiere Pro exporting a video to work with 2016 version of Windows Media Player

Hi guys... so I have no idea what to do here but I need to figure out a way to get a video to work for a client that is using an ancient version of windows... I am confident there is nothing I can do in the export for this? but is there anything I can do to the video post export to make it work for them and run in their version of Windows Media Player? Any help would be greatly appreciated. Alternatively is there any recommendation I can give to my client on a player they could download? Although this would be avoided preferably as I would like to solve the problem for them myself
