I'm new to cudafy.NET and I'm trying to get an existing application using cudyfy.NET v1.27 to work on my local machine.
My webapplication is build using VS2013 Express C#, I also have VC++ 2010 Pro installed for the compiling. I have a GeForce 840M card with CUDA and OpenCL.
The Cudafy Viewer is working fine for the CUDA and OpenCL setup.
My webapplication is working fine if I use OpenCL but not when I use CUDA.
I had a lot of issues with it, most are solved but now I've got this error:
Access denied for C:\Program Files (x86)\IIS Express\
At least this means that it is working since it is creating a .cu file, but in the wrong location.

I've been using Google to find an option to change the location but can't find it. I would have expected this file in the bin folder of my application or in my tmp folder.

Any help is much appreciated.

Have you tried putting the CUDAfy.NET dll into the GAC? If you use the Cudafy Module Viewer tool there is a link to a site informing you how to do this.
You could also use the WorkingDirectory property.

Thanks Nick,

I had already put the CUDAfy.NET dll into the GAC. Setting the WorkingDirectory property worked.
I use the CUDAfy.NET dll in a webservice using a solution with multiple projects/dlls.
When I run my service in Visual Studio and start a second Visual Studio instance to run my unit test it works, after I place the dll (GPUService.Common.dll) that does the GPU stuff in C:\Program Files (x86)\IIS Express\

But when I start my service using this script:
start /B "GPUServices" "C:\Program Files (x86)\IIS Express/iisexpress" /site:GPUServices
and open my solution in Visual Studio and run my unit test I get an error saying it cannot found GPUService.Common.dll
Using ProcMon I can see it is looking for this dll in several places, also in C:\Windows\Microsoft.NET\Framework\v4.0.30319\
When I copy my GPUService.Common.dll into this folder as well, all works again.

So I'm happy everything is working now, but I don't know why I need to copy the dll to those system folders. I don't need to this for my other webservices or webapplications that don't use the CUDAfy.NET dll.
