Make sure you have the requirement software (both free):
- DirectX End-User Runtime: http://www.microsoft.com/en-us/download/confirmation.aspx?id=8109
- Visual C++ Redistributable: https://www.microsoft.com/en-us/download/details.aspx?id=48145
In case you're using a PC with both integrated graphics and a dedicated graphic card, go to Nvidia Control Panel (or AMD Settings) and set LifePlay.exe to use your dedicated graphic card
