Win10 x64 Blender building w/MSVC2017 and CUDA kernel error

Hello,

Could anybody explain such error-just appeared today after former succesfull build:

cuew init fialed (0xffffffff) cycles_kernel_cuda
initialization error, exiting cycles_kernel_cuda

Got latest CUDA Toolkit 9.2 - its because of this?

UPDATE - SOLVED !
Yes, its CUDA 9.1 to be installed instead.
