installing Cuda NVIDIA Graphic Driver failed
I have two laptops: a Sony vaio z-series (vocz1) & S series. The first one has Geforce with cuda model GT330M and second one has GT 640M LE. When I am trying install CUDA Geforce driver from this site http://developer.nvidia.com/cuda/cuda-downloads I am receiving below error in Windows. I am wondering would you suggest me a solution to solve this issue? all of my graphic card already installed,
Nvidia installer cannot continue This graphics card could not find compatible graphics hardware.
I am beginner in programming with CUDA, I want to know can I compile and run my CUDA program with out installing Nividia Driver? Cuda toolkit and SDK installed successfully in my machine but whenI run my program I cannot set my Cuda device. Does it mean I need to install Nividia Driver? 
cudaError_t cudaStatus1;
int deviceCount;
cudaGetDeviceCount(&deviceCount);
int device;
for (device = 0; device < 10; ++device) {
cudaDeviceProp deviceProp;
cudaGetDeviceProperties(&deviceProp, device);
// Choose which GPU to run on, change this on a multi-GPU system.
cudaStatus1 = cudaSetDevice(device);
printf("Device %d has compute capability %d.%d. - %dn",
device, deviceProp.major, deviceProp.minor,cudaStatus1 );
}
output:
Device 0 has compute capability 3137268.3137268. - 35
Device 1 has compute capability 3137268.3137268. - 35
Device 2 has compute capability 3137268.3137268. - 35
Device 3 has compute capability 3137268.3137268. - 35
Device 4 has compute capability 3137268.3137268. - 35
Device 5 has compute capability 3137268.3137268. - 35
Device 6 has compute capability 3137268.3137268. - 35
Device 7 has compute capability 3137268.3137268. - 35
Device 8 has compute capability 3137268.3137268. - 35
Device 9 has compute capability 3137268.3137268. - 35
35 means it is not set the device , if it became 0 means device set.
after I run deviceQuery below information I received:

You will definitely need drivers to run the program. Have you tried running deviceQuery.exe provided with the binaries. That should give you a good starting point as to what is going wrong.
I have a VAIO too and I had the same problem. Don't download notebook version, try Desktop version of Nvidia Driver. I also had to disable my another Graphic card (Intel). It worked for me.
Unfortunately, there are many NVIDIA GPUs for which the driver from the NVIDIA website will not install (especially for GPU versions that are specifically OEM'd for Sony, Lenovo, etc and the OEM wants to control the driver experience). This is most likely the case for you.
In those cases, you can edit the .inf file to add your GPU into the list of GPUs for which the driver will install. However, it is a bit tricky and typically requires editing 3 different sections of the INF file. You can search around for details on how to mod NVIDIA inf files; there are a number of sites that do that.
Of course, you have to have the appropriate CUDA driver before you can run CUDA stuff. So first things first... you've gotta get the driver installed.
