I have just installed the CUDA SDK 4.0, and all the .sln file won’t open because the .vcproj files refer to a missing file NvCudaRuntimeApi.rules. I’ve searched my ENTIRE C: drive for this, and indeed for all .rules files in all folders, including the CUDA SDK folder and the VC folders, and it’s not there. Is there a way to get this file put in the right place?
