DirectPlay is a function that is needed to run latest as well as old games on Windows 10.
Even after installing DirectX 9.0c the only directX requiured for playing even the latest games..Some times older games(for example IGI2 ) give error that DirectX 8.1 is needed to run the game. Most Latest version of DirectX like ver 11 or ver 12 are present inside the graphics drivers.
To enable it…
Go to Control Panel and select uninstall a program
After this go to the left preview pane and select Turn Windows Features on and off as shown below.
I am using Windows 10 in this case. After this Go to legacy components and Check DirectPlay there.
Finally DirectPlay is Enabled and you can Enjoy your game..:)
