You need to have these 2 services running:
1. NVIDIA Driver Helper Service
2. NVIDIA Update Service Daemon
If you've disabled them manually, restart them, or uninstall and reinstall your nvidia drivers.
You should be able to check in Nvidia Control panel. Should be a option to select graphics processor to use with this program, it might be set to use integrated graphics but you'll want to switch it to use nvidia high-performance NVIDIA processor.
It might autodetect wrong depending where you have your monitor or monitors plugged in. I.e make sure the monitor is plugged into your graphics card.
