Hello,
If you've ever lost your Sony's OEM Programs, VAIO Care may help. But not always. As if you've installed VAIO Care on your Sony PC, it can sometimes show: Reinstall Applications and Drivers. It means you need to use a Recovery Media. BUT WHAT IF YOU DO NOT HAVE IT??? Reinstalling the program certainly won't help. Maybe reinstalling Windows could help to make the program work properly. 🙂
