Cudafy.Net System.ComponentModel.Win32Exception: The system cannot find the file specified

Question

I downloaded cudafy here: https://github.com/lepoco/CUDAfy.NET/releases/tag/v.1.0.0. I use VS 2022, .NET 4.8. When executing this code, I get System.ComponentModel.Win32Exception.

            CudafyModes.Target = eGPUType.Cuda;
            CudafyModes.DeviceId = 0;
            CudafyTranslator.Language = CudafyModes.Target == eGPUType.OpenCL ? eLanguage.OpenCL : eLanguage.Cuda;

            if (CudafyHost.GetDeviceCount(CudafyModes.Target) == 0)
                throw new System.ArgumentException("No suitable devices found.", "original");

            GPGPU gpu = CudafyHost.GetDevice(CudafyModes.Target, CudafyModes.DeviceId);

            CudafyModule km = CudafyTranslator.Cudafy(); //THE EXCEPTION IS HERE
            gpu.LoadModule(km);

StackTrace:

The Path environment variable is declared:

Cuda Toolkit 11.6 has been downloaded.

What can I do about it?

That's not enough information to go on, try examining the properties on the exception: https://learn.microsoft.com/en-us/dotnet/api/system.componentmodel.win32exception?view=net-6.0 — satnhak, Jan 16 '22 at 16:27
OK, so you have a file not found exception: https://learn.microsoft.com/en-us/windows/win32/debug/system-error-codes--0-499- — satnhak, Jan 18 '22 at 11:48
This is perhaps an obvious question, but have you got the CUDA toolkit installed? — satnhak, Jan 18 '22 at 11:51

I solved the problem by connecting the source code. In particular, the program did not find the path to the utility vswhere.exe. Also the CUDA Toolkit required VS2010.
