'No cuda device is found' on Windows 8.1, CUDA 6.0 and drivers 332.88 and newest

I got problem with 740M on my laptop: I can not run applications after windows was updated to 8.1. Everything before worked nice. I have tried to reinstall some versions of drivers and SDK and nothing helped. I tried option in driver installator ‘make clean install’ (or something like this) and it did not help.
Also, GPU-Z shows that cuda is not enabled on my 740M.
Please, give me anything to deal with this.
Thanks in advance!

Same here, did nVidia dump CUDA in favor of NVENC and now we’ll have to upgrade all our apps if they ever add NVENC support?
