Posting here because I also encountered this problem and just could not get ENB to work at all on W10 using all the standard advice - installing the 2010 DX SDK and redistributables, installing the DX libraries included in /skyrim/DirectX10, running everything in administrator mode, etc - nothing worked. For what it's worth, I'm on a 980TI and noticed a couple other people in the threads about this problem who weren't able to solve it were too, so I think there's probably a hardware specific hiccup some of us are running into. No matter what, I always got the application failed to start error as soon as I launched, with a preset or just ENBoost. However, EighmyLupin suggested a couple years ago on a different thread to try this mod: https://www.nexusmods.com/skyrim/mods/33227/? I don't have an optimus card, and can't tell you why this fixed the problem. But dang it absolutely works now. I saw at least one other user in a different thread reporting the same - nothing worked till they tried this fix. Also, critically: I tried this fix earlier and it didn't work, because my computer was stuck on Windows 10 1803. You *need* to be on 1809, the creator's update, for these fixes to apply. There are other fixes for memory issues in DX9 games included in the recent windows updates you want anyway - you won't be able to allocate more than 4GB of video memory to ENB without them. I know this is an old thread, but it looks like people still bump into this issue from time to time and it was one of the first Google results for me. If the advice above for updating your OS, drivers, and DX 2010 SDK/redistributables didn't work, try out this mod.
