Please inform me about the title filled above.
I don't think Mah Jong Medley is available to play it on Windows 8.1 64bit, since there is no download available on the official website. The listed developer is Gamehouse, but their website doesn't contain anything about it which I believe that Mah Jong Medley is discontinued.
I recommend choosing other applications from the same category: http://software.informer.com/search/mahjong
