How do I know if CUDA is installed on Geforce 560 Ti?

Trying to get CUDA to work on my Nvidia Geforce 560 Ti. Installed the local version of CUDA to my Windows 7 computer.

How can you tell if CUDA has been installed correctly?

I see some samples but cannot seem to be able open any of them.

Looking at steps 6 & 7 of the CUDA quick start guide I see instructions ‘Navigate to the CUDA Samples nbody directory’ and ‘Open the nbody Visual Studio solution file for the version of Visual Studio you have installed’. I cannot seem to open these files to verify.

Do you have visual studio installed?

Install visual studio and then install cuda kit from nvidia’s site after that try opening the samples via visual studio.
