No, there is no version of Solkan Solitaire available for Windows 8. I have Windows 8.1 Pro x64 installed and downloaded the game. When launched, it says that Windows can't open this app. I have applied compatibility tweaks, but the message was the same. You will need to use other Solitaire application.
